Abstract

The developed Leydig cells-conditioned medium (LCM) contains bioactive materials secreted by Leydig cells in vitro.  LCM was used to evaluate the ability of bone marrow mesenchymal stem cells differentiation. Bone marrow mesenchymal stem cells (1x 106 cell/ml) were cultured in : 1) DMEM supplemented with 10% NBCS as a control (M), 2) M supplemented with 10 ng/ml testosterone; 3) M supplemented with 50%  LCM ; 4) M supplemented with 50% LCM and 2.5 IU/ml hCG. Bone marrow mesenchymal stem cells that were cultured with  LCM has a positive reaction (57.4%) to histochemistry staining 3β-HSD and produced 1.87 ng/ml testosterone. Supplementation of hCG to LCM  increased the positive number of Leydig cells and testosterone production by 74.6% and 12.33 ng/ml (P<0.05). It can be concluded that Leydig cells-conditioned medium can support differentiation of bone marrow mesenchymal stem cells into Leydig cells.

Abstract

Implantation is the most critical stage in the establishment of pregnancy. In mammals, it has been estimated that between 25% and 60% of conceptuses are lost before or at the time of implantation. The objectives of  this study were to investigate  the ability of blastocyst hatching and attachment of trophoblast cells in in vitro, the outgrowth and differentiation of trophoblast cells in in vitro culture of hatched and non hatched blastocyst, the activity of mitochondria NADH-CoQ reductase and the pattern of mitochondrial distribution. Blastocysts were collected from mice cornua utery at day-4 of pregnancy and were divided into 3 groups: blastocysts undergo hatching within 24 hours, 48 hours and non hatching. Embryos were cultured in DMEM medium in 5% CO2 incubator at 37°C for 10 days. The trophoblasts monolayer were processed for Giemsa staining and histochemistry analysis of NADH-tetrazolium reductase activity. The outgrowth of trophoblast cells were measured using eyespiece micrometer. The results showed the ability of blastocyst hatching in in vitro were different. The trophoblast outgrowth diameter of 24 h hatched blastocyst was significantly different with the 48 h hatched and non hatched blastocyst. The activity of NADH-CoQ reductase of 24 h and 48 h hatched blastocysts showed higher intensity than the non hatched blastocysts (P<0,05) and the distribution of mitochondrial in trophoblast cell cytoplasma of 24 h and  48 h hatched blastocyst were homogen around nucleus whereas thoes of non hatched blastocyst were cluster and heterogen. In conclusion, in in vitro study the failure of blastocysts hatching and implantation was due to the failure of outgrowth and differentiation of the trofoblast cells and the impairment of NADH-CoQ reductase activity in complex I mitochondria to produce energy and the pattern of mitochondrial distribution.Key words: mitochondrial distribution, NADH- tetrazolium reductase, trophoblast, implantation

Abstract

The aims of the study were to investigate the influence of FSH and the ovary cutting treatments on the development of primordial follicles into preantral and antral follicles. Ovaries were grouped as whole ovary (without cutting); partially cut ovary and completely cut ovary (hemi ovary). All ovary groups were cultured in Dubellco?s Modified Eagle Medium (DMEM) containing 5ug/ml insulin, 10ug/ml transferrin, 5ug/ml selenium (ITS), 5% FBS, 50ug/ml gentamycin with and without 100uIU/ml Follicle Stimulating Hormone (FSH). Cultures were done in 5% CO2 incubator at 37oC. Results showed that after 8 days in vitro cultured in DMEM containing FSH, the average number of preantral follicles isolated from each whole, partially-cut and completely-cut ovaries were 16.1 + 3.3, 26.8 ± 7.7 and 12.3 + 1.9, respectively. On the other hand, those cultured in DMEM without FSH they were 17.3 + 3.8, 23.3 ± 5.2 and 17.8 + 2.8, respectively. After additional cultured for 8 days, the percentage of preantral follicles developing into the antral follicles in DMEM with and without FSH were 26.7 + 5.7 and 11.7 + 2.9, respectively. In conclusion, the supplementation of FSH in the culture medium did not increase the number of preantral follicles, but significantly increased the number of antral follicles. The ovary cutting treatment significantly increased the average number of collected preantral follicles.

Abstract

Antifungal Activity of Cumin Oil Against Candida parapsilosis SS25, C. orthopsilosis NN14, C. metapsilosis MP27, and C. etchellsii MP18. Many kinds of spices are used in Indonesia, one of them is white cumin seed. This spice is used not only for cooking, but also for traditional medicine. This study reported of antifungal activity from white cumin’s essential oil. Extraction and identification of Cumin oil were carried out. We obtained 2.5-3.0% of white essential oil which was colorless or light yellow color. GCMS analysis revealed that there were 12 peaks. Based on peak’s intensity the oil were dominated by 4 compound i.e. cuminaldehide (35.44%), ρ-cymene (34.77%), β-pynene (15.08 %) and γ-terpinene (8.15%). Growth inhibition zone determination has been carried out by diffusion disc and direct method against yeast i.e. C. parapsilosis SS25, C. orthopsilosis NN14, C. metapsilosis MP27, and C. etchellsii MP18. The results showed that all of the yeasts were sensitive to cumin oil. The inhibition zone radius were 13.4-16.5 mm. The cumin oil showed the inhibition of yeast growth with MIC values of 0.028%-0.042% and MFC values 0.09%- 0.14%, while nystatin had MIC values 0.40%-0.50% and MFC values 3.0%-4.0%. The activity of cumin oil was very strong as antifungal.
