ABSTRACT
Background and Aims: The covid-19 pandemic has reversed years of progress in the fight to end tuberculosis. So, the discovery of new drugs as antituberculosis is very much needed. Our previous studies have shown that the extract of Centella asiatica is able to inhibit the growth of Mycobacterium tuberculosis in vitro and requires further research. The aims of this study is to prove the effect of Centella asiatica inhibit Mycobacterium tuberculosis in rat model tuberculosis. Method(s): The protocol in this study was approved by the veterinary ethics committee of Airlangga University. The rat tuberculosis model was induced by intrathecal injection of a suspension of Mycobacterium tuberculosis strain H37 Rv. Twenty-eight tuberculosis rat were randomly divided into four groups. Groups 1,2, and 3 were treated with ethanol extract of Centella asiatica at 375 mg/kgBW, 750 mg/kgBW and 1500 mg/kgBW, and the fourth group was the control group. Centella asiatica extract is administered orally via an intragastric feeding tube for two weeks, once daily At the end of the experimental period, rats were sacrificed by cervical decapitation. The left lung tissue was taken aseptically and cultured on Middlebrook 7H10. Result(s): The results showed that there was no bacterial growth on the culture media in the group that received Centella asiatica extract at a dose of 750 and 1500 mg/kg BW. Conclusion(s): The conclusion in this study, that Centella asiatica extract inhibit the growth of Mycobacterium tuberculosis at doses of 750 and 1500 mg/kg BW.

ABSTRACT
Destructive operations diminish the bulk of the foetus for facilitating vaginal delivery. Procedures such as craniotomy or decapitation can be carried out to deliver a dead baby in appropriately selected cases. Ours is a retrospective case series at a single tertiary facility during the first wave of the COVID pandemic. From July 2020 to January 2021, six destructive operations (five craniotomies and one decapitation) were performed in women who had arrest of descent in the second stage of labour but had intrapartum foetal demise. The average operative time was 30â minutes with a mean hospital stay of 4.3 days, which was significantly less than CS, and with much less morbidity. None of these women had significant post-partum haemorrhage or sepsis. Destructive procedures should be considered for better obstetric future of the patient, and a lesser burden on the health facility. What was practiced in COVID times should be extended beyond.
ABSTRACT
AIM: Levamisole, an antiparasitic drug, was reported to have positive effects in various clinical trials in the treatment of COVID-19. However, the number of studies on the effects of levamisole on the reproductive system and sexual behavior in male rats is limited. The present study aimed to investigate the possible effects of levamisole on sexual behavior, testicular histopathology, serum gonadotropin, and testosterone levels in male rats. METHODS: Twenty male Sprague-Dawley rats were divided into two groups as control and levamisole were used. Rats were given levamisole (2 mg/kg) dissolved in distilled water for 30 days, while only distilled water was administered to the control group by oral gavage. Finally, sexual behavior tests (SBT) were performed for 30 min. Then, the animals were decapitated, blood samples and testis tissues were taken. The Bax, Hsp70 and cytochrome c immunohistochemistry staining were performed in testis tissues, and gene expression levels were measured by real-time PCR. The luteinizing hormone (LH), follicle-stimulating hormone (FSH), and testosterone levels were measured by ELISA in serum samples. RESULTS: In SBT parameters, mount latency (ML, p<0.001), intromission latency (IL, p<0.01), and the postejaculatory interval (PEI, p<0.01) were significantly prolonged. Also, the copulatory rate (CR, p<0.05) was significantly reduced. Serum LH, FSH, and testosterone levels did not change. In the histopathological stainings, irregularities in the seminiferous tubule germinal epithelium, congestion, edema in the interstitial area, and metaphase arrest in some spermatocytes were detected in the levamisole group (p<0.001). Levamisole treatment also significantly increased cytochrome c, Bax, and Hsp 70 immunoreactivities and Bax (p=0.05) and Hsp 70 (p<0.01) gene expression levels in testicular tissue. CONCLUSION: Levamisole may decrease sexual motivation and copulation efficiency. Also, it may adversely affect testicular histopathology in male rats.
