Abstract

Circadian rhythm is the adaptation response of animals against light alteration that affects various behavioral and physiological responses. Bright light is a danger signal for nocturnal animals because it exposes them more to predators. This research aimed to study the changes in the behavior of rats during the partial solar eclipse (PSE) period. The PSE period occurred across Bogor, Indonesia, on 9 March 2016. The PSE started at 06.19 AM, peaked at 07.21 AM, and ended at 08.30 AM. The light level decreased since the early solar eclipse, then dropped significantly at the peak period. The activities of six mature male Sprague Dawley rats were measured using Opto-Varimex-5 Auto Track System during the PSE period. The measurements were repeated one day after the PSE period as the non-PSE period. There were significant differences (P<0.05) in stereotypic time, burst of stereotypic movement, and horizontal count in the early, peak, and end periods of the PSE period compared with the values at the same time of the non-PSE period. The activities of rats changed during the PSE period. Rats did not rest as in their normal nocturnal behavior during darkness but were more active and stressed because of the rapid change in light level during the PSE period.

Abstract

Kerusakan ginjal berdampak pada proses eritropoiesis karena ginjal merupakan organ utama penghasil eritropoietin (EPO). Tanaman kumis kucing secara turun-temurun sudah digunakan untuk pengobatan gangguan saluran kemih, hipertensi, dan diabetes mellitus. Tanaman ini diketahui mengandung berbagai zat aktif yang bersifat nefroprotektif, seperti flavonoid, tannin, saponin, phenol, serta terpenoid. Penelitian ini bertujuan untuk melihat potensi tanaman kumis kucing untuk memperbaiki profil eritosit pada kondisi kerusakan ginjal yang diinduksi oleh etilen glikol. Sebanyak 35 ekor tikus galur Sprague Dawley jantan berumur 7 bulan dibagi ke dalam 7 kelompok perlakuan dengan pemberian etilen glikol dan atau ekstrak kumis kucing dengan lama permberian yang berbeda. Pemberian ekstrak daun kumis kucing mampu meningkatkan jumlah eritrosit pada tikus serta menekan penurunan jumlah eritrosit saat dan setelah pemberian etilen glikol. Selain itu, pemberian ekstrak kumis kucing juga mampu menurunkan jumlah leukosit serta rasio neutrofil: limfosit yang meningkat akibat induksi etilen glikol. Ekstrak kumis kucing memiliki potensi untuk memperbaiki proses eritropoiesis dan menekan peradangan pada kasus kerusakan ginjal.

Abstract

This study, the impact of Bacillus subtilis probiotics on the productivity and faecal microbial variable of commercial laying hens in Indonesia was investigated. A total of 100,296 laying hens aged 18 weeks in a close house system were randomly allocated into two treatments with four replications per treatments. The applied treatments were T0 (control) and T1 (feed with probiotics). The experiment involved feeding laying hens with/without Bacillus subtilis strains 747 and 1781 (bacterial load of 1.5x108 cfu/kg feed, strain ratio of 1:1), collecting data on egg production, egg weight, feed consumption, and depletion from 20 to 26 weeks. Those variable were also observed from 18 to 19 weeks as pre-treatment data. Faecal samples were collected at 26 weeks for analysis of Escherichia coli, Clostridium perfringens, and lactic acid bacteria levels. The results revealed that administering Bacillus subtilis strains 1781 and 747 significantly increased daily egg production by 7.9% and reduced daily depletion by 65% at the end of the treatment phase. However, probiotic supplementation did not affect daily feed intake, feed conversion ratio, egg weight, or the levels of E. coli, C. perfringens, and lactic acid bacteria in the hens' faeces. These findings demonstrate the potential and feasibility of Bacillus subtilis strains 1781 and 747 in improving the productivity and health of laying hens of commercial-scale production. This information is valuable for the poultry industry in optimizing production practices. Key words: AGP, Bacillus subtilis, laying hen, probiotic, productivity

Abstract

Physalis angulata L. (ciplukan) is traditionally used as an herbal remedy with anticancer and antioxidant properties. At the same time, busulfan, a chemotherapy alkylating agent, causes gonadotoxicity and oxidative stress that impair female reproduction. This study aimed to evaluate the effect of P. angulata on reproductive function after busulfan administration in female rats. Twenty-five 6-week-old female rats were randomly divided into: Group I (control), Group II (busulfan only), Group III (P. angulata only), Group IV (busulfan followed by P. angulata after 14 days), and Group V (busulfan and P. angulata administered for 28 days). FSHR and LHR expression in the ovaries and MDA levels in the ovaries and uterus were measured to assess reproductive changes. Busulfan showed no significant effect on FSHR and LHR, whereas P. angulata induced downregulation, suggesting a potential negative feedback mechanism on ovarian receptors. Ovarian MDA showed a decreasing trend with combined treatments, while uterine MDA peaked after busulfan but declined markedly with P. angulata, indicating its role in alleviating oxidative stress. In conclusion, P. angulata may modulate hormonal balance in rat ovaries and decrease oxidative stress in the uterus after busulfan treatment.
