"Lactobacillus plantarum FNCC-0461 merupakan bakteri asam laktat yang diisolasi dari dadih, yang berpotensi sebagai probiotik. Probiotik menunjukkan manfaat jika memiliki viabilitas minimal 1 x 10⁷ CFU di ileum distal atau kolon. Namun, sebagian besar probiotik tidak tahan terhadap kondisi ekstrim selama melalui saluran cerna. Enkapsulasi probiotik menjadi sediaan pelet tertarget kolon menjadi solusi yang baik untuk menjaga viabilitas dan memberikan pelepasan probiotik ke lokasi spesifik di kolon. Pelet diformulasikan menggunakan metode ekstrusi-sferonisasi dengan eksipien berupa Microcrytalline Cellulose (MCC), laktosa, pektin, Cellulose Acetate Phthalate (CAP) dan shellac. Sediaan pelet yang telah dibuat dievaluasi karakteristik fisik, viabilitasnya hingga dilakukan uji disolusi selama 24 jam pada pH 1,2; 6,8 dan 7,4. Pelet yang dilapisi CAP menunjukan hasil yang paling optimum dengan karakteristik pelet yang berbentuk bulat dengan distribusi ukuran partikel 913,57 ± 8,28 μm dan persen perolehan kembali 88,71 ± 1,04 % yang memiliki sifat alir yang sangat baik, kekuatan mekanik yang baik, viabilitas 4,76 x10⁷ CFU/g dan hasil uji disolusinya menunjukan pelepasan sel tertinggi pada cairan simulasi kolon sebesar 1,38 x 10⁷ CFU/g setelah 24 jam.

Lactobacillus plantarum FNCC-0461 is a lactic acid bacteria isolated from dadih which has potential as a probiotic. Probiotics show health benefits if they have viability at least 1 x 10⁷ CFU in the distal ileum or colon. However, most probiotics are not resistant to extreme conditions while passing through the digestive tract. Encapsulation of probiotics into colon-targeted pellets was a good solution to maintain the viability and provide release of probiotics to specific site in the colon. Pellets were formulated using extrusion-spheronization method with excipient such as Microcrystalline Cellulose (MCC), lactose, pectin, Cellulose Acetate Phthalate (CAP) and shellac. The obtained pellets were evaluated for their physical properties, viability and dissolution study was carried out at pH 1.2; 6.8 and 7.4 for 24 hours. CAP-coated pelet provide the optimum formulation were spherical with particle size distribution was 913.57 ± 8.28 μm and yield was 88.71 ± 1.04 %, it’s have very good flow properties, good mechanical properties, viability was 4.76 x10⁷ CFU/g and it’s dissolution study showed the highest cell release in simulated colonic fluid of 1.38 x 10⁷ CFU/g for 24 hours."

"Pengembangan penghantaran tertarget kolon bertujuan agar pelepasan obatnya mencapai target terapetik yang selektif sehingga dapat memaksimalkan efeknya baik dengan tujuan pengobatan secara sistemik maupun lokal. Lactobacillus plantarum FNCC 0461 yang telah dikembangkan dalam bentuk sediaan pelet dapat menjadi alternatif dalam terapi diare yang menjadi salah satu target penyakit dengan pengobatan tertarget kolon. Optimasi formula penyalut dilakukan untuk mendapatkan profil pelepasan obat yang lebih baik berdasarkan parameter persen kumulatif pelepasan probiotik melalui uji disolusi dengan medium yang menyerupai kondisi saluran pencernaan. Pelet yang dilapisi Cellulose Acetate Phthalate (CAP) dengan konsentrasi 5% menunjukkan profil pelepasan obat yang lebih baik dibandingkan konsentrasi 7,5% dan 10% selama pengamatan 24 jam dengan nilai masing-masing sebesar 50,5%; 24,3% dan 18,0%. Nilai tersebut sebanding dengan jumlah sel viabelnya dimana CAP dengan konsentrasi 5% > 7,5% > 10% dengan nilai masing-masing sebesar 3,45±0,520x107; 1,5±2,598x107 dan 1,05±2,598x107. Hasil uji secara in vivo menggunakan hewan uji tikus jantan galur Sprague Dawley menunjukkan bahwa kelompok hewan uji yang mendapat perlakuan sediaan pelet tertarget kolon yang mengandung L.plantarum FNCC-0461 mengalami perbaikan setelah dilakukan induksi E. coli dibandingkan kelompok lainnya. Efektivitas ini dinilai berdasarkan parameter farmakodinamiknya, terutama nilai rata-rata intensitas BAB sebesar 4,67±0,52 kali dengan konsistensi feses berada pada skala 0 (bentuk padat) diakhir pengamatan serta kandungan kadar air sekum rata-rata sebesar 43,52±2,177%. Keberhasilan lain juga terlihat dari perubahan berat badan yang lebih stabil, nafsu makan yang meningkat, nilai total BAL yang lebih tinggi, dan total E. coli yang lebih rendah dari kelompok lainnya. Penelitian ini menunjukkan bahwa formulasi sediaan pelet tertarget kolon dengan konsentrasi CAP 5% yang mengandung L. plantarum FNCC-0461 memiliki efektivitas sebagai antidiare.

The development of colon-targeted delivery aims to ensure that the drug release reaches selective therapeutic targets so that it can maximize its effects for both systemic and local treatment purposes. Lactobacillus plantarum FNCC 0461 which has been developed in pellet dosage form can be an alternative in diarrhea therapy which is one of the disease targets with colon-targeted treatment. Optimization of the coating formula was carried out to obtain a better drug release profile based on the cumulative percent parameter of probiotic release through a dissolution test with a medium that resembles the conditions of the digestive tract. Pellets coated with CAP (Cellulose Acetate Phthalate) with a concentration of 5% showed a better drug release profile than concentrations of 7.5% and 10% during 24-hour observation with a value of 50.5% each; 24.3% and 18.0%. This value is proportional to the amount of cell viability where CAP with a concentration of 5% > 7.5% > 10% with respective values of 3.45 ± 0.520x107; 1.5±2.598x107 and 1.05±2.598x107. In vivo test results using male Sprague Dawley rat test animals showed that the group of test animals treated with colon- targeted pellets containing L. plantarum FNCC-0461 experienced improvements after E. coli induction compared to other groups. This effectiveness was assessed based on pharmacodynamic parameters, especially the average defecation intensity value of 4.67 ± 0.52 times with fecal consistency being on a scale of 0 (solid form) at the end of the observation and an average cecum water content of 43.52 ± 2.177 %. Other successes were also seen from more stable weight changes, increased appetite, higher total BAL values, and lower total E. coli than the other groups. This research shows that a colon- targeted pellet formulation with a CAP concentration of 5% containing L. plantarum FNCC-0461 has been proven to be effective as an antidiarrheal."

"Latar Belakang: Candida albicans merupakan penyebab utama infeksi mikroba oportunistik pada pasien kanker. Pasien Leukemia Limfositik Akut (LLA) yang menjalani kemoterapi memiliki risiko tinggi terkena kandidiasis karena imunosupresi dan melemahnya barier epitel. Penggunaan obat antifungal sistemik dibatasi oleh risiko efek samping yang lebih besar dan berkembangnya strain yang resisten, namun obat antifungal topikal yang tersedia saat ini masih dianggap kurang efektif untuk pasien imunosupresi termasuk pasien kemoterapi. Beberapa penelitian memberikan bukti kelayakan probiotik Lactobacillus casei untuk bertindak sebagai antifungal alternatif di berbagai sistem organ manusia. Tujuan: Menganalisis pengaruh probiotik terhadap jumlah C. albicans di rongga mulut anak penderita LLA selama kemoterapi. Metode: Sampel saliva diambil dari 11 anak penderita LLA selama kemoterapi. Subyek diinstruksikan untuk berkumur dengan probiotik yang mengandung L. casei selama 60 detik, dua kali sehari, selama 14 hari. Sampel saliva tidak terstimulasi dikumpulkan secara berurutan pada 3 titik waktu (awal, 7 hari, dan 14 hari). Jumlah C. albicans dihitung dengan qPCR. Hasil: Perbedaan signifikan secara statistik ditemukan antara jumlah C. albicans pada awal (494.363+180.737 CFU/ml), setelah 7 hari (276.654+69.903 CFU/ml), dan setelah 14 hari (229.286+50.883 CFU/ml) berkumur dengan probiotik. Jumlah yang lebih rendah secara signifikan ditemukan setelah 7 dan 14 hari berkumur dengan probiotik (p<0.05). Kesimpulan: Probiotik L. casei memiliki efek menurunkan jumlah C. albicans di rongga mulut anak leukemia selama kemoterapi.

Background: Candida albicans is the leading cause of opportunistic microbial infections in patients with cancer. Acute Lymphocytic Leukemia (ALL) patients undergoing chemotherapy have high risk of candidiasis due to immunosuppression and weakened epithelial barriers. Systemic antifungal drugs’ usage is limited by the greater risk of side effects and developing resistant strains, yet currently available topical antifungal drugs are still considered ineffective for immunosuppressed patients including chemotherapy patients. Several studies provide evidence for the feasibility of probiotic Lactobacillus casei to act as alternative antifungal in various human organ systems. Objectives: To analyze the effects of probiotic L. casei on the number of C. albicans in oral cavity of children with ALL during chemotherapy.Methods: Saliva samples were taken from 11 children with ALL during chemotherapy. Subjects were instructed to do mouth rinse with probiotics contained Lactobacillus casei for 60s, twice daily, over the course of 14 days. Unstimulated saliva samples were collected sequentially at 3 time points (baseline, 7 days, and 14 days). The number of C. albicans was quantified by qPCR. Results: Statistically significant differences were found between the number of C. albicans at baseline (494.363+180.737 CFU/ml), after 7 days (276.653+69.903 CFU/ml), and after 14 days (229.286+50.883 CFU/ml) mouth rinsing with probiotic L. casei. Significant lower number was found both after 7 and 14 days rinsing with probiotics (p<0.05). Conclusion: Probiotic L.casei has reducing effects on the number of C. albicans in oral cavity of children with ALL during chemotherapy. "

"Ruminants are herbivorous mammals that have special digestive tract, rumen, where digestion of cellulose and polysaccharides can be carried out by rumen microorganisms. Methanogenic bacteria in the rumen using H2 compounds results from anaerobic fermentation of carbohydrates to form methane. Methane production in the rumen is an energetically wasteful process, since the feed intake will be converted to methane and eructated as gas (Bunthoen, 2007). Rumen protozoa have a potential role in the process of digestion and breakdown of organic material. Hydrogen (H2) as one of the protozoa fermentation products are used by methanogenic bacteria to form methane. This causing methanogenic bacteria often found living attached to the surface of protozoa to keep a constant supply of hydrogen. The purpose of this study is to enumerate the number of methanogenic bacteria and protozoa with different diet and after the addition of probiotic Lactobacillus plantarum TSD-10 in vitro. This report consist of two parts, which are (1) Effect of Feeding Composition on Total Methanogenic Bacteria and Protozoa Rumen, and (2) Influence of Probiotic Lactobacillus plantarum TSD-10 on Total Methanogenic Bacteria and Protozoa In Vitro. The research was conducted at the Laboratory of Industrial Microbiology, Research Centre of Biotechnology? Indonesian Institute of Sciences (LIPI), Cibinong Bogor, from September 2008 ? May 2009. The treatment are diet A with ratio of grass : concentrate (30 : 70) and diet B with ratio of grass : concentrate (70 : 30). The probiotic L. plantarum TSD-10 dose are 0%, 5%, 10% and 15% v/v. The number of methanogenic bacteria obtained from diet A ranges between (0,74 ? 0,89) x 107 cfu/ml, whereas in diet B ranged from (1,71 ? 2,58) x 107 cfu/ml. Methanogenic bacteria average on feed B ((2,19 ± 0,44) x 107 cfu/ml) higher than the feed A ((0,82 ± 0,07) x 107 cfu/ml). Based on the Analysis of Variance (ANOVA), different composition of diet A and B, significantly affect the number of methanogenic bacteria ( 5%), with the best diet composition in suppressing the growth of methanogenic bacteria is diet A. The number of methanogenic bacteria in diet B are higher since the value of a more alkaline pH (8). According to Mirzaei-Aghsaghali et al. (2008), methanogenic bacteria are sensitive to changes in pH. Decrease in pH value will decrease the number of methanogenic bacteria and cause less methane gas produced. The low number of methanogenic bacteria on diet A, can also be caused by the ratio of acetate : propionate obtained lower than in diet B, and it also causes a lower pH of the diet A (Lana et al., 1998). The ANOVA showed the methanogenic bacteria average between diet A and B in the morning and afternoon sampling significantly different between treatments ( 5%), with the best treatment in suppressing methanogenic bacteria from each sampling were diet A. Increased methanogenic bacteria after feeding may be associated with the presence of protozoa in the rumen cilliata that serves as a producer of hydrogen and bacterial attachment to methanogen. Composition diet B low in fiber and high in starch are preferred by the protozoan (Leedle and Greening, 1988). The number of protozoa obtained from the diet A ranges between (1,93 ? 3,95) x 105 cells/ml, whereas the diet B ranged from (2,81 ? 4,35) x 105 cells/ ml. Protozoa average on diet B ((3,76 ± 0,83) x 105 cells/ml) higher than the diet A ((3,08 ± 1,04) x 105 cells/ml). Based on the ANOVA, differences composition diet A and B, not significantly different between treatments (5%). Diet B with a higher pH value causes no influential ration of protozoa, which does not cause a decrease in the number of protozoa. The ANOVA indicate that the average range of protozoa between diet A and B are significantly different (5%) in the morning sampling, with the best treatment in suppressing the number of protozoa are diet A. The afternoon sampling, ANOVA showed that the treatment was not significantly different (5%). Protozoa observed in treatment diet A and B are families of, Ophryoscolecidae, Isotrichidae and Blepharocorythidae. Most number obtained from each diet is Ophryoscolecidae, while the less is Blepharocorythidae. This is due to Ophryoscolecidae a part of the Order Entodiniomorphida who compiled most of rumen cilliata. In the contrary, Family Isotrichidae and Blepharocorythidae are part of the order Trichostomatida which is rarely found in rumen (Ogimoto and Imai, 1981). Decreasing in the number of methanogenic bacteria in the diet B (56,8%) higher than diet A (29,8%), while the decrease in the number of protozoa in the diet B (64,9%) higher than diet A (62,7% ). Diet B with a higher concentrate composition can provide a change in the pattern of rumen fermentation. These changes make the environment less suitable for methanogenic bacterial growth. One of the unfavorable change is a reduction of rumen pH values (Moss et al., 2000). On the addition of probiotics in vitro, the ANOVA showed the range of the number of methanogenic bacteria was not significantly different ( 5%) on the variations of diet A and B but significantly different (5%) on the number of protozoa, with the best in suppressing the growth of protozoa are diet A. Variations doses of probiotic significantly different (5%) on the number of methanogenic bacteria and protozoa, with the best dose 5% v/v to suppress methanogenic bacteria and 15% v/v to suppress protozoa in vitro. Feed Digestibility Coefficient (FDC) shows the FDC from 27,99 ? 31,95%, while the diet B ranged from 25,85 to 31,3%. In diet A, the value FDC obtained tended to increase (8,5%) along with increasing concentration of probiotic L. plantarum TSD-10. Increasing FDC value expected to suppress the growth of methanogenic bacteria by altering the rumen fermentation pattern which results in volatile fatty acids produced. Diet A shows the value of higher acetate than propionate, because diet A high on fiber that will support the growth of the acetate-producing bacteria species, diet B rich in starch that supports the growth of propionic-producing bacteria species, and marked by increasing propionate than acetate (France and Dijkstra, 2005)."
