Chitosan, a modification of shrimp-shell waste, has been utilized as microcapsule. However, it’s fragile gel property needs to be strengthened by adding glutaraldehyde (glu) and natural hydrocolloid guar gum (gg). This research’s purposes were to study dissolution behaviour of ketoprofen and infar through optimum chitosan-guar gum microcapsule. Into 228.6 mL of 1.75% (w/v) chitosan solution in 1% (v/v) acetic acid,38.1 mL of gg solution was added with concentration variation of 0.35, 0.55, and 0.75% (w/v) for ketoprofen microcapsules and 0.05, 0.19, and 0.33% (w/v) for infar microcapsules, and stirred with magnetic stirrer until homogenous. Afterwards, 7.62mL of glu was added slowly under stirring, with concentrations varied: 3, 3.5, and 4% (v/v) for ketoprofen microcapsules, and 4, 4.5, and 5% (v/v) for infar microcapsules. All mixtures were shaked for 20 minutes for homogenization. All mixtures wereshaked for 20 minutes for homogenization. Into each microcapsule mixture for ketoprofen, a solution of 2 g of ketoprofen in 250 mL of 96% ethanol was added, whereas solution of 100 mg of in 250 mL of 96% ethanol was added into each microcapsule mixture for infar. Every mixture was then added with 5 mL of 2% Tween-80 and stirred with magnetic stirrer for an hour at room temperature. Everymixture was then added with 5 mL of 2% Tween-80 and stirred with magnetic stirrer for an hour at room temperature. Conversion of suspension into fine powders/granules (microcapsules) was done by using spray dryer. The data of [gg], [glu], and medicine’s content from each microcapsule were treated with Minitab 14 software to obtain optimum [gg] and [glu] for microencapsulation. The dissolution behaviour of optimum ketoprofen and infar microcapsules were investigated. The result of optimization by using Minitab Release 14 software showed that among the microcapsule compositions of [gg] and [glu] were 0.35% (w/v) and 3.75% (v/v), respectively, optimum to coat ketoprofen, whereas [gg] and [glu] of 0.05% (w/v) and4.00% (v/v), respectively, optimum to coat infar, at constant chitosan concentration (1.75% [w/v]). In vitro dissolution profile showed that chitosan-guar gum gel microcapsule was more resistant in intestinal pH condition (rather basic) compared with that in gastric pH (very acidic).

The research was carried out to study the effect of egg-yolk consentration and cholesterol suplementationto tris - 1.2% maltosa extender on the quality of frozen semen of garut rams. Semen was collected once a week using artificial vagina from six mature Garut rams. Semen was equilibrated at 5oC for three hours, frozen and stored in liquid nitrogen. The thawing was carried out at the temperature 30oC for 30 seconds. Percentages of motility and intact plasma membrane (IPM) parameters were evaluated every stage of freezing semen. The results show that there were no interaction between both treatmenst on the quality of garut rams frozen semen. In the cholesterol treatment, percentages of progressive motile sperm and intact plasma membrane in control (50,50% and 57,92%) were significantly different (P<0,05) than cholesterol 1,0 mg /100 ml treatment (37,08% and 49,42%) respectively. In conclusion, addition of 10% egg yolk concentrationto TrisÃ‚Â Ã¢â‚¬â€œ1.2% maltosa extender was not significantly different than 20% egg yolk concentration. The frozen semen quality of control produced the best quality semen compared toboth addition of 0.5mg/100 ml and 1.0 mg/100 ml cholesterol treatments. Cholesterol addition to egg yolk TrisÃ‚Â Ã¢â‚¬â€œÃ‚Â 1.2% maltosa causes degradation of frozen semen quality.Penelitian dilakukan untuk melihat pengaruh konsentrasi kuning telur dan penambahan kolesterol pada pengencer semen Tris dengan maltosa 1,2% terhadap kualitas semen beku domba garut. Semen dikoleksi seminggu sekali dengan vagina buatan dari enam domba garut jantan. Semen diekuilibrasi pada suhu 5Ã‚Â oC selama tiga jam kemudian dibekukan dan disimpan di dalam nitrogen cair. Metode thawing dilakukan pada suhu 30oC selama 30 detik. Parameter persentase motilitas dan membran plasma utuh dievaluasi pada setiap tahap pembekuan. Hasil penelitian menunjukkan bahwa tidak ada interaksi antara kedua perlakuan terhadap kualitas semen beku domba garut. Perlakuan kolesterol menunjukan bahwa persentase motilitas dan membran plasma utuk pada perlakuan kontrol (50,50% dan 57,92%) lebih tinggi dan berbeda nyata dibandingkan perlakuan1,0 mg/100ml kolesterol (37,08% dan 49,42%). Penambahan kuning telur 10% pada pengencer Tris dengan maltosa 1,2% menghasilkan kualitas semen tidak berbeda dengan penambahan kuninf telur 20%, Penelitian menyimpulkan bahwa kualitas semen beku terbaik diperoleh pada perlakuan kontrol lebih tinggi dibandingkan perlakuan kolesterol 0,5 mg/100 ml dan 1,0 mg/100 ml. Penambahan kolesterol akan menurunkan kualitas semen beku domba garut.Keywords:Ã‚Â cholesterol, motility, membrane plasm, garut ram, spermatozoa.
