Abstract

Injection of female mammalian animals with gonadotropin prior to mating using superovulation dose increases estradiol 17beta (E2) synthesis and secretion and improves the growth and development of the uterus to support prenatal growth with the side effect of increasing litter size. This experiment was designed to study the effects of low doses of PMSG injection in heifers on the growth of granulose cells (GC) of pre-ovulatory follicles, E2 synthesis, and uterine glands growth and development. Nine Ongole-grade heifers were divided into three groups of doses of PMSG injection, i.e., 0 IU/kg BW, 0.5 IU/kg BW, and 1.0 IU/kg BW. The injection of pregnant mare serum gonadotropin (PMSG) was conducted at the early stage of the second follicle wave. Blood samples were collected at estrus (day 0) to measure plasma E2 concentrations. The ovary and uterus were collected for histological observation after slaughtering the animal. The results showed that non-superovulation doses of PMSG injections at the second follicle wave significantly increased the growth of GC that eventually produced a significantly higher plasma E2 concentration by 39.47% and 113.57%, in heifers receiving 0.5 IU/kg BW and 1.0 IU/kg BW (p<0.05), respectively. The increase in E2 synthesis and secretion significantly stimulated the growth and development of uterine glands (p<0.05), which was reflected in the improved measures of uterine glands. In conclusion, injections of heifers with low doses of PMSG at the second follicle wave could increase the growth of GC to produce a higher secretion of E2 that eventually improves the growth and development of uterine glands in the endometrium without the risk of multiple calving.

Abstract

In estrous synchronization, the hormone progesterone is an important element. Various hormone preparations currently available have limitations, especially those related to environmental impact issues. Various alternatives are being studied, and using biodegradable polymeric materials (chitosan-polyethylene glycol combination) to develop new devices is considered one of the solutions. This contribution aims to design and evaluate intravaginal implants that can release progesterone and be degraded in the body and the environment. Implants are made by melting and molding techniques. In vitro drug release studies using dyes as drug models. Implant degradation studies tested in compost. Changes in the shape of the implant, while it is in the vagina, are observed by ultrasound. Blood collection was performed three days before and during implantation to obtain a blood progesterone profile. In vitro drug release studies using dye as a drug model showed a chitosan-PEG profile that released the drug faster at first, then slowed down. Implant degradation studies in compost and vagina demonstrated a gradual degradation process. The blood progesterone profile increased during implantation, as high as 15 ng/mL on the third day. In conclusion, the chitosan-PEG intravaginal implant formulation designed using the melting and molding technique proved to be degraded in the compost environment. It released the hormone progesterone for four days according to the degradation period of the implant in the vagina.
