"ABSTRAK Pendahuluan. Osteoarthritis (OA) adalah sebuah penyakit sendi degeneratif yangmenyebabkan disabilitas dengan prevalensi yang terus meningkat. Hormonpertumbuhan memiliki efek regenerasi tulang rawan secara langsung melaluistimulasi sel kondroblas dan proses morphoangiogenesis juga melalui faktorpertumbuhan secara sistemik. Penelitian ini bertujuan untuk mengetahui manfaatsuntikan sendi dengan hormon pertumbuhan pada kasus Osteoarthritis. Metode Penelitian. Penelitian dilakukan di Rumah Sakit Hewan InstitutPertanian Bogor pada bulan Mei hingga September 2015. Desain penelitian adalahrandomized post test only control group. Sejumlah 21 ekor kelinci Selandia Baruputih, berat 1.9-2.6kg, usia 7-8 bulan. Kelinci dibagi secara acak menjadikelompok kontrol (NaCl 0.9%), suntikan hormon pertumbuhan (4iu), dan suntikanasam hyaluronat (6mg) . Dengan metode acak tersamar dilakukan suntikankolagenase tipe II C. Histolyticum pada hari 1 dan ke 4 pada lutut kiri, kemudiantindakan penyuntikan dilakukan sebanyak tiga kali dengan selang waktu 1minggu. Evaluasi dengan periode kepincangan, skoring makroskopis, histologisdilakukan pada minggu ke-8 pasca penyuntikan pertama. Temuan Penelitian. Berdasarkan hasil penelitian ditemukan periode kepincanganpada grup yang diberikan hormon pertumbuhan lebih singkat, dan bermaknasecara statistik dibandingkan dengan grup kontrol (p<0.001), grup asamhyaluronat (p<0.03), dan grup hormon pertumbuhan (p<0.001). Evaluasi skormakroskopik dengan skor yoshimi menunjukan bahwa kelompok hormonpertumbuhan memiliki kerusakan tulang rawan yang lebih ringan jikadibandingkan dengan grup kontrol (p=0.001) dan grup asam hyaluronat (p=0.04).Skoring histopatologis menggunakan skor modifikasi Mankin menunjukan padakelompok dengan hormon pertumbuhan memiliki angka terendah dibandingkangrup lainnya (p=0.001), grup kontrol (p=0.001), grup asam hyaluronat (p=0.015).

" adalah salah satu penyebab penurunan performa fisik pada seseorang yang melakukan program latihan fisik jangka panjang. Kondisi overtraining dihubungkan dengan gangguan dalam regenerasi sel tubuh. Insulin-like growth factor-I (IGF-I) adalah protein yang menstimulasi pertumbuhan dan proliferasi sel. IGF-I bekerja dalam regulasi aksis GH/IGF, dimana kerja IGF dipengaruhi oleh growth hormone (GH) dan insulin-like growth factor binding protein-3 (IGFBP-3). Penelitian ini bertujuan untuk mengetahui respons tubuh terhadap latihan fisik aerobik overtraining dengan menganalisa kadar GH, IGF-I, dan IGFBP-3, mengingat hormon dan protein ini berperan dalam regenerasi sel tubuh, khususnya otot rangka. Subjek penelitian adalah 19 ekor tikus putih jantan galur Wistar (berusia 8-10 minggu, berat 150-250 gr) yang dibagi menjadi 3 kelompok (satu kelompok kontrol dan dua kelompok yaitu kelompok aerobik dan kelompok aerobik overtraining yang diberikan perlakuan masing-masing selama 11 minggu). Perlakuan latihan fisik aerobik dan aerobik overtraining dilakukan dengan Animal treadmill L-6000 sebanyak lima hari dalam seminggu. Setelah hari terakhir perlakuan, seluruh hewan coba dikorbankan. Serum darah diambil dengan cara pungsi jantung. Kadar GH, IGF-I, dan IGFBP-3 dalam serum diukur dengan metode ELISA dan data hasil penelitian dianalisis dengan one way ANOVA dan dilanjutkan dengan uji Post Hoc. Hasil pemeriksaan ELISA menunjukkan kadar IGFBP-3 yang lebih rendah secara signifikan pada kelompok aerobik overtraining dibandingkan dengan kelompok aerobik, sementara tidak ada perbedaan kadar GH dan IGF-I pada ketiga kelompok. Kadar IGFBP-3 dalam serum dapat dipertimbangkan sebagai penanda biologis kondisi overtraining.

Overtraining is one of the causes of decline in physical performance in long-term physical exercise program. Overtraining is associated with impaired regeneration of body cells. Insulin-like growth factor-I (IGF-I) is a stimulator of cell growth and proliferation. IGF act based on the GH/IGF axis, which mean IGF-I act is regulated by growth hormone (GH) and insulin-like growth factor binding protein-3 (IGFBP-3). This study purpose is to determine the body's response to aerobic overtraining exercise by analyzing the levels of growth hormone (GH), insulin-like growth factor-I (IGF-I), and insulin-like growth factor binding protein-3 (IGFBP-3) as those hormone and proteins play a role in the regeneration of body cells, especially skeletal muscle cells. Subjects were 19 white male rats of the Wistar strain (8-10 weeks old, weight: 150-250 g) were divided into 3 groups (one control group and two groups of aerobic and aerobic overtraining group both were given treatment for 11 weeks). Aerobic exercise and aerobic overtraining exercise treatment were conducted five days a week using Animal treadmill L-6000. After the last day of treatment, all experimental animals were sacrificed. Blood serum collected by cardiac puncture. Levels of GH, IGF-I and IGFBP-3 in serum were measured by ELISA. The data were analyzed by one-way ANOVA followed by post hoc test. ELISA results showed significant lower levels of IGFBP-3 in aerobic overtraining group compared to the aerobic group, while there was no difference in the levels of GH and IGF-I in all groups. IGFBP-3 levels in the serum may be a suitable as biological markers for overtraining condition."

"ABSTRACTStunting or short stature in children is a significant nutritional problem in developing and underdeveloped countries. Stunting during childhood might affect brain development and impair development cognitive function. Additionally, this condition associated with the increased risk for obesity during adulthood. Several studies have shown that the increment risk of obesity and overweight in children with a short stature was due to their metabolic efficiency. Children with stunting have lower resting energy expenditure compared to non stunting children. Additionally, stunted children has higher respiratory quotient and carbohydrate oxidation but lower fat oxidation compared to non-stunting children. These results might explain why stunted children easily become obese, which is due to lower fat oxidation and leading to tendency to store fat.This review discussed the current status on studies in the nutrigenetic aspects of the relationship between stunting in the childhood and obesity in adulthood. I hypothesized that stunted children are more likely to become obese in their later life because they have lower metabolic rate and higher tendency of fat storage. There are several candidate genes and pathway involved in obesity and I suspected that ghrelin and its receptor growth hormone secretague receptor (GHSR) were responsible."
