Subjective and objective observation of Tilapia skin as auto skin graft dressing in cats.

Background: The recovery of auto skin graft is a dynamic and complex process that requires a suitable environment for vascularization as nutrition delivery to cells and donor skin reception. Aims: This research aimed to determine the effect of Tilapia skin dressing on the recovery of auto skin graft treatment on domestic cats through subjective and objective observation. Methods: Six male Indonesian local cats aged 1-2 years old weighing 3-4 kg were separated into two groups. The surgical procedure was performed in a sterile and aseptic environment. The first surgery created wound defects on the forelimb area 2 × 2 cm in size to whole groups. The wounds were left for 4 days and then treated with the following treatments; Group I (G-I) was treated with Tilapia skin dressing, and Group II (G-II) was treated with moist dressing Sofra-tulle®. The dressing of the two groups was replaced every 3 days and evaluated subjectively and objectively. Results: Subjective observation showed that skin was reddish (day 3), the bleeding test showed bleeding immediately occurred after incision, and pain response was observed on day 6 post-surgery on both treatment groups showed significantly differences with 95% confidence level (p < 0.05). Objective observation in the form of NaCl 0.9% absorption and medicine effect on auto skin graft did not show a significant difference between the two treatment groups (p > 0.05). Conclusion: Auto skin graft treatment by moist dressing showed better healing, but Tilapia skin dressing can be an alternative choice during auto skin graft treatment.

Identification of cellulolytic lactic acid bacteria from the intestines of laying hens given AKBISprob based on 16S ribosomal ribonucleic acid gene analysis.

Background and Aim: Supplementation of AKBISprob (developed in a previous study) in feed can improve production efficiency and poultry health, especially laying hens. In addition, it can also increase cellulolytic lactic acid bacteria (LAB) in chicken intestines, but these bacteria are still unknown; thus, they need to be identified. This study aimed to identify cellulolytic LAB in the intestines of laying hens administered AKBISprob based on 16S ribosomal ribonucleic acid (16S rRNA) gene analysis. Materials and Methods: The samples used in this study were 13 LAB isolates from the intestines of laying hens that were given AKBISprob 4%. Cellulolytic LAB DNA was isolated and 16S rRNA gene was amplified by polymerase chain reaction, followed by sequencing, bioinformatics analysis, and phylogenetic tree construction. Results: From 10 cellulolytic LAB isolates with a clear zone of >6 mm, four were selected and their DNA was amplified with BaCF and UniB primers ~1500 bp DNA fragments. Of these, the P31H62 isolate was genetically close to Enterococcus hirae strain 1-1X-16 with 92.90% maximum identity, the P33S52 isolate had homology with Enterococcus mundtii strain ZU 26 with 96.76% maximum identity, and the P33S62 isolate was closely related to E. hirae strain SJ3 with 72.96% maximum identity. The phylogenetic tree revealed that the cellulolytic LAB isolates P31H62 and P33S52 were in one cluster closely related to the genus Enterococcus. Conclusion: This study suggests that the isolates P31H62, P33S62, and P33S52 from the intestines of laying hens administered 4% AKBISprob are cellulolytic LAB belonging to the genus Enterococcus.

Immunohistochemical Expression of AQP2 and HSP70 in Broiler Kidney Tissue Treated with Salix tetrasperma Roxb. Extract under Heat Exposure.

The administration of plant extracts to broilers may be a way to mitigate the effects of heat stress. The importance of AQP2 and HSP70 compounds in maintaining the homeostasis of the chicken body when it is subjected to heat stress is well established. This study aims to determine the effect of giving the ethanolic extract of the leaves of Salix tetrasperma Roxb. on the immunohistochemical expression of AQP2 and HSP70 in exposed and unexposed broiler kidney tissue. This study used 36 samples of 28-day-old chicken kidneys. Chickens were kept in individual cages, provided with feed and drinking water ad libitum. The design used was a completely randomized design with 6 treatments and 6 replications: (a) chickens were reared in conditions exposed to heat (HS + 0); (b) chickens were reared in conditions exposed to heat and given Salix extract at a dose of 50 mg/L drinking water (HS + 50); (c) chickens were reared under heat-exposed conditions and given Salix extract at a dose of 100 mg/L drinking water (HS + 100); (d) chickens were reared in conditions without exposure to heat (n-HS + 0); (e) chickens were reared in conditions without exposure to heat and given Salix extract at a dose of 50 mg/L drinking water (nHS + 50); and (f) chickens were reared in conditions exposed without exposure to heat and given 100 mg/L drinking water (nHS + 100) of Salix extract. Salix extract was given for 24 hours and was renewed every 6 hours. The results showed that giving Salix extract 100 mg/L in drinking water to chickens exposed to heat (HS + 100) reduced the value of the H/L ratio. Giving Salix extract 50-100 mg/L in drinking water caused an upregulated AQP2 expression; on the other hand, it downregulated HSP-70 expression, in chicken kidney tubules both exposed to heat stress and nonexposed to heat stress. In conclusion, exposure to heat stress in broiler chickens and giving Salix extract can increase the formation of aquaporin 2 compounds and suppress the formation of HSP70.

Neem Leaf (Azadirachta indica A. Juss) Ethanolic Extract on the Liver and Kidney Function of Rats.

Neem (Azadirachta indica A. Juss) is one of the tropical plants found in Indonesia that has been used to prevent and treat various diseases. This study aimed to investigate the effect of the ethanol extract of neem leaves on the concentration of aspartate aminotransferase (AST), alanine aminotransferase (ALT), urea, and creatinine in male rats. Twenty-four male Wistar rats were randomly divided into four groups (T0, T1, T2, and T3) with 6 rats in each group. T0 is the control group, and T1, T2, and T3 are the treatment groups that were administered 100, 200, and 300 mg/kg body weight of neem leaf ethanolic extracts for 48 days, respectively. On day 49, blood samples were collected to measure the concentration of AST, ALT, creatinine, and urea followed by an evaluation of liver and kidney histology. The results showed that the ethanolic extract of neem leaves did not affect the concentration of AST, ALT, and creatinine, The ethanol leaves reduced extract on the urea concentration, no abnormal changes were observed in the liver and kidney organs. In the future, it is required to carry out a comprehensive safety evaluation of the neem leaf ethanol extract for herbal medicines.

The concentration of testosterone, pituitary adenylate cyclase-activating polypeptide, and protamine 1 in the serum of male chicken following administration of epididymis and testicular extracts and their combination.

BAKCGROUND AND AIM: Testis and epididymis are male reproductive organs that play an important role in spermatogenesis. These two organs are rich in the content of hormones and other molecules needed in the process of spermatogenesis which affect the quality of the spermatozoa. The objective of this study was to examine the effect of the administration of epididymis and testicular extracts and their combination on testosterone, pituitary adenylate cyclase-activating polypeptide (PACAP), and protamine 1 (PRM1) concentrations in the serum of male chicken. MATERIALS AND METHODS: Twenty male chickens (broiler strain Cp707), aged 3 weeks and weighing 800-1000 g, were randomly divided into four different groups including a control group (T0) = injected with 1 ml normal saline and treatment groups: T1 = injected with 1 ml epididymis extract, T2 = injected with 1 ml testicular extract, and T3 = injected with a combination of 1 ml epididymis + 1 ml testicular extract. The experiment was conducted for 13 days and at the end of the study (day 14), the chickens were sacrificed to obtain the serum. Furthermore, the concentrations of testosterone, PACAP, and PRM1 were then measured by using an enzyme-linked immunosorbent assay technique. RESULTS: The concentrations of PACAP and PRM1 did not show a significant difference between treatment groups (T1, T2, and T3) and control group (T0) (p>0.05). However, the concentration of testosterone showed a significantly higher difference in a group injected with a combination of 1 ml epididymis and 1 ml testicular extracts (T3) compared to the control group (T0) (p<0.05). CONCLUSION: The administration of epididymis and testicular extracts and their combination did not affect the increase of PACAP and PRM1 concentration. However, a combination of these extracts significantly affects the increase of testosterone concentration in the serum of male chicken.
