Abstract. Many types of stress, including psychological stress, nega-tively affect reproductive health. This study aimed to investigate the ef-fects of sertraline (a selective serotonin reuptake inhibitor), cerebrolysin (neuroprotective/neurotrophic), and a combination of both against stress-induced ovarian damage, infertility and pregnancy delay in female rats. The rats were divided into five groups (n=14/each group) as healthy (HG), stress control (StC), stress+sertraline (SS), stress+cerebrolysin (SC), and stress+sertraline+cerebrolysin (SSC). To induce stress, animals (except the HG) were kept in a supine position with their forelimbs and hindlimbs (FIM) tied for one hour. Then, sertraline (20mg/kg) was given orally to the SS. Cerebrolysin (2.5ml/kg) was injected into the SC subcutaneously. Sertraline+cerebrolysin was administered to SSC with the same methods and doses. FIM and drug administration continued for 30 days. Six rats from each group were euthanized with high-dose anesthesia, right and left ovarian tissues were removed, and tissues were examined biochemically and histopathologi-cally. The remaining rats were taken for breeding. Exposure to stress in rats caused an increase in malondialdehyde (MDA), tumor necrosis factor-alpha (TNF-α), interleukin-1β (IL -1β), and interleukin-6 (IL -6) levels and a decrease in total glutathione (tGSH). Stress was related to histopathological damage, infertility, and delayed birth. The sertraline and cerebrolysin combination was the most effective in preventing these changes, with sertraline and cerebroly-sin alone in second and third places, respectively. Regarding efficacy, selective serotonin reuptake inhibitors (SSRIs) and related drugs may be beneficial in treating stress-related ovarian damage, infertility, and delay in pregnancy.

Can Covid-19 attack our nervous system?

Nowadays, Covid-19 is considered a serious health problem worldwide. Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is a novel human coronavirus that has sparked a global pandemic of the coronavirus disease of 2019 (COVID-19). It is well known that the Corona Virus attacks mainly the respiratory system. Meanwhile, it has been established that coronavirus infection can extend beyond the respiratory system and unfortunately, can also affect our nervous system. Multiple neurological symptoms and signs had been documented during and post covid conditions. This virus gets access to the central nervous system (CNS) via the bloodstream leading to infect the endothelial lining cells. Also, it was reported that the virus can enter the peripheral nervous system via retrograde neuronal routes. The virus could be internalized in nerve synapses through endocytosis, transported retrogradely, and spread trans-synoptically to other brain regions. This minireview highlights the possible routes by which SARS-CoV-2 can invade the central nervous system (CNS) and its pathophysiology and manifestation.

Diabetes mellitus (DM) is a complicated condition that is accompanied by a plethora of metabolic symptoms, including disturbed serum glucose and lipid profiles. Several herbs are reputed as traditional medicine to improve DM. The current study was designed to explore the chemical composition and possible ameliorative effects of Ocimum forskolei on blood glucose and lipid profile in high-fat diet/streptozotocin-induced diabetic rats and in 3T3-L1 cell lines as a first report of its bioactivity. Histopathological study of pancreatic and adipose tissues was performed in control and treatment groups, along with quantification of glucose and lipid profiles and the assessment of NF-κB, cleaved caspase-3, BAX, and BCL2 markers in rat pancreatic tissue. Glucose uptake, adipogenic markers, DGAT1, CEBP/α, and PPARγ levels were evaluated in the 3T3-L1 cell line. Hesperidin was isolated from total methanol extract (TME). TME and hesperidin significantly controlled the glucose and lipid profile in DM rats. Glibenclamide was used as a positive control. Histopathological assessment showed that TME and hesperidin averted necrosis and infiltration in pancreatic tissues, and led to a substantial improvement in the cellular structure of adipose tissue. TME and hesperidin distinctly diminished the mRNA and protein expression of NF-κB, cleaved caspase-3, and BAX, and increased BCL2 expression (reflecting its protective and antiapoptotic actions). Interestingly, TME and hesperidin reduced glucose uptake and oxidative lipid accumulation in the 3T3-L1 cell line. TME and hesperidin reduced DGAT1, CEBP/α, and PPARγ mRNA and protein expression in 3T3-L1 cells. Moreover, docking studies supported the results via deep interaction of hesperidin with the tested biomarkers. Taken together, the current study demonstrates Ocimum forskolei and hesperidin as possible candidates for treating diabetes mellitus.
