Abstract

Series of exploratived laboratory experiment have been conducted to analysed the bioactifity of Insulin Like Growth Factor – I (IGF-I) Complex protein of goat seminal plasm on the membran plasm and acrosom cap of centrifugation sperm. First experiment was conducted to identificatify and isolate IGF –I Complex of goat seminal plasm by using Native - Polyacrylamide gel electroforesis. The result of analysis of Native – PAGE indicated that IGF-I Complex have molecular weight of 150 kDa. Second experiment was conducted to role of IGF-I Complex protein on the membrane plasm and acrosom cap of centrifugation sperm. Semen was collected by using artificial vagina from eight mature goat. Immediately after initial evaluation, semen was centrifugated with Bracket and Oliphant’s (BO) for 5 minutes 1800 rpm. And then divided two groups. Each group was supplemented with 3 × 106 of sperm concentration and then into group I was supplemented with BO medium and group two was supplemented with IGF-I Complex protein. The result of this experiment indicated that percentages of intact plasm membrane and intact acrosom cap were significantly (p < 0.05), between BO medium and IGF-I protein. In conclusion, IGF- I Complex protein is the optimal in improving plasm membran and acrosom cap of centrifugation sperm

Abstract

The teratogenisity mechanism of boric acid is less known. There are contradictory observation on the effect of boric acid on the fetus malformation. An observation reported that boric acid is bound to the riboflavin and this complex causes a riboflavin deficiency on fetus. However, the other observation suggested that the present of riboflavin and boric acid had no decresed malformation on fetus, but increased malformation. It is giving an idea that the one of teratogenisity mechanism of boric acid may the biological mechanism to the target cells. The goal of this study was to evaluate the effect of boric acid on the growth and development of cultured chick embryo chondrocytes. Chondrocytes were dispersed from sternal cartilage of 12-d chick embryos (Gallus gallus). Randomized completely design was used to arrange this treatment with five replicates for each treatment. The dosage of boric acid were 10, 20, 40, 60, 80, and 100 μg/ml. The cultures were observed on 1, 3, 5, 7, 9 day after boric acid treatment, including: the cell proliferation, cell adhesion, cell attachment and colony formation. The data were analyzed descriptively. Result of this experiment showed that on high dose (80 and 100 μg/ml) cell adhesion was not formed, therefore the colony was not formed, and formed vacuola in the cell. This study indicated that boric acid on the high dose can inhibit the cell proliferation, cell adhesion, cell attachment and colony formation.

Abstract

Biosurfactant, microbial metabolite whose properties like surfactant, was suggested to replace chemically synthesized surfactant for take in hand environtmental pollution by petroleum hydrocarbon. This work was done to examine potency of Pseudomonas sp. isolated from Tanjung Perak Harbor to produce biosurfactant. Also, to know the effect of different substrates (glucose + yeast extract, lubricating oil and hexadecane) toward biosurfactant production. Pseudomonas sp. grown in mineral synthetic water and biosurfactant production was measured on stationary phase. Biosurfactant production based on emulsification activity and surface tension reduction of supernatant (using Du Nouy tensiometer). Solar, lubricating oil, and hexadecane were used to examine emulsification activity. Results indicated that Pseudomonas sp. have a potency to produce biosurfactant. Surface tension of supernatant decreased up to 20 dyne/cm, when grown on hexadecane substrate. Hexadecane is the best growing substrate for biosurfactant production than others.

Abstract

The experiment was conducted the potential of antiibody sperm to spermatogenesis and fertility of the male rat. Ten of rat testis have been used in this research, then crushed and added with 10 cc saline and then were filtrated and centrifuged 1800 rpm for ten minutes. Twenty four of the male rat divided in to four groups. Group I: injected with saline 0.1 cc/sc/day for 45 days; group II: injected with testis suspension 0.1 cc/sc/day for 15 days; group III: injected with testis suspension 0.1 cc/sc/days for 30 days; group IV: injected with testis suspension 0.1 cc /sc/days for 45 days. Then each of the male rat were mated with female, then the number of the total of pups were counted. Male rat were killed and testis were collected for preparation of histology and count of the spermatocyte and spermatid. The results show that the number of the spermatocyte and spermatid has significant different in the group and control (p < 0.05). The number of the pups significantly different in the group and control (p < 0.05). Implication of this research was injected Antibodisperm on male rat can decrease of the number of spermatocyte, spermatid and the number of the pups.

Abstract

The aims of this research were to know the ability of recombinant xylanolytic enzyme from recombinant E. coli DH5a (pTP510) to hydrolyze several commercial xylan and analysis the reduction sugar product. Recombinant xylanolytic enzyme (exo-xylanase, b-xylosidase and a-L-arabinofuranosidase) could hydrolyzed several commercial xylan (oat-spelt xylan, birchwood, wheat, rye, and arabinan) with xylanolytic activities are: oat-spelt xylan (1.73 U/mL), birchwood (0.92 U/mL), wheat (6.52 U/mL), rye (4.94 U/mL), and arabinan (3.40 U/mL). Xylanolytic enzyme assay use specific substrate p-nitrophenyl-b-D-xylopyranoside (pNP-X) shown xylosidase activity 15.869 U/mL. Hydrolysis product was analyzed by HPLC. The results showed that xylose, arabinose, and xylo-oligosaccharide were produced from birchwood, wheat, rye, and arabinan hydrolysis, although xylose and arabinose were produced from hydrolysis of oat-spelt xylan.
