Abstract

Cryopreservation process could affect spermatozoa quality during from reactive oxygen species (ROS) produced in cellular metabolism and the environment. Spermatozoa damage caused by ROS during cryopreservation can be reduced with the addition of natural antioxidant which commonly found in fruits like date palm. This research was done to investigate the influence of date extract on semen quality after cryopreservation. This experimental study used a completely randomized design with 4 treatments and 6 replications. Semen collected from two aceh cattle bulls was diluted in tris egg yolk extender contained different concentrations (v/v) of date extract: 0% (P0, control), 0.75% (P1), 1% (P2), and 1.25% (P3) before cryopreserved at -196 ºC for 7 days. Semen quality prior to and after cryopreservation as well as sperm DNA integrity were determined by standard microscopic and laddering methods, respectively. The results showed that the addition of 1% date extract could maintain viability (68.67%), plasma membrane integrity (62.33%), and abnormality (18.58%) of aceh cattle spermatozoa, but unable to maintain its motility above 40%. There was no DNA fragmentation observed in both treated and fresh semen. This is the first study investigates the influence of supplementation of date palm extract on preserved aceh cattle spermatozoa diluted in egg yolk tris based extender.

Abstract

Providing scientific evidences for the medicinal benefits and possible toxic effects of the flamboyant flowers (Delonix regia (Bojer ex Hook.) Raf.) are very important to implementing the medicinal plant in this modern era. This study aimed to investigate antidiabetic potential of methanol extract of flamboyant flowers using a completely random design. Twenty-four male rats were randomly divided into 6 treatment groups with 4 replications: healthy rats (normal control, P1), diabetic rats treated with flamboyant flower extract of 0 (negative control, P2), 100 (P3), 200 (P4), and 400 mg/kg BW (P5), and rats which were induced by 0.45 mg/kg BW of Glibenclamide (positive control, P6). Diabetic condition was achieved by a single injection of alloxan 150 mg/kg BW. Treatments were given once a day for 14 days. On day 0, 3 and 18 blood samples were withdrawn from rats’ orbital vein for glucose measurement. All rats were sacrificed for liver, gastrocnemius muscles and pancreatic tissues collection. The liver and gastrocnemius muscle were subjected for glycogen measurement whereas pancreatic tissues were processed for histological examinations. Data was analyzed by ANOVA and followed by Duncan test. The results showed that flamboyant flowers extracts significantly (p0.05) reduced blood glucose as well as degeneration and necrosis of pancreatic β cells. Optimal dose to decrease blood glucose and pancreatic cell degeneration was 200 mg/kg BW; whereas optimum dose to decrease pancreatic cell necrosis was 400 mg/kg BW. In conclusion, flamboyant flower extract can reduce blood glucose in rats. This is the first that shows antidiabetic potential of local Flamboyant flower extracts along its toxicity effect to pancreatic tissues. These information could become a basic consideration for the use of the plant extracts as a candidate to cure patients with diabetic problems.

Abstract

Aceh swamp buffaloes (Bubalus bubalis) are decreasing their population and genetic quality. This study was conducted to determine the influence of lactose and glycerol cryoprotectants on spermatozoa of Aceh swamp buffaloes after thawing. This study used completelya factorial randomized design with nine treatments, and five replications. Fresh semen of the Aceh swamp buffalo were diluted by using a combination extender lactose cryoprotectants 0 mM (L0), 60 mM (L60), 120 mM (L120) and glycerol 3% (G3), 5% (G5), 7% (G7) with the equilibration of 4 hours. The results showed that the combination of cryoprotectants L120G7 influenced significantly (P 0.05) on the quality of spermatozoa of the Aceh swamp buffalo (B. bubalis) after  thawing. The percentage of sperm motility L120G7 (42.60 ± 1.14); viability L120G7 (55.00 ± 0.71);  acrosome integrity L120G7 (52.00 ± 0.71); and plasma membrane integrity L120G7 (53.20 ± 1.48).  The combination of lactose cryoprotectants 120 mM (L120) and glycerol 7% (G7) was the best combination to maintain the quality of spermatozoa of swamp buffalo. This finding could be used to define a policy for the spermatozoa storage of Aceh swamp buffalo to artificial insemination (AI).

Abstract

Preservation of ovarian tissue from severely injured or dead valuable animals has the potential to preserve female germ cells of animals. The ability to mature and fertilize of oocytes from preserved ovary of endangered species will allow us to sustain genetic and global biodiversities. The aims of this study were to investigate the viability of oocytes collected from the preserved ovary and its potential utilization for the production of cat embryos followed by in vitro maturation and fertilization. Ovary was preserved immediately in phosphate buffer saline (PBS) at 4 °C for 24 or 48 hours. The quality and viability of oocytes after the maturation process were identified microscopically using aceto-orcein staining. Biological function of the oocytes was evaluated by using in vitro culture technique for the maturation and fertilization rate in CR1aa medium culture. The results showed that the percentage of oocytes collected from preserved ovary for 24 and 48 hours that remained at the stage of metaphase-II were 29.4% and 21.9% respectively. Fertilization rates produced in the IVF using oocytes collected from ovary preserved for 24 or 48 hours were significantly lower (30%) than that of unpreserved control (36.7%). In conclusion, female germ cells of cat ovary preserved at 4 °C in PBS for 2 days were still viable for in vitro fertilization and thus can be utilized for in vitro production of cat embryos. Information obtained can be used as a basis of knowledge of using a combination of physiological reagent and cold-based preservation technique in modern reproductive technology for animals.
