Objectives

The increase in pharmaceutical drug consumption and the presence of these drugs in the environment causes concern about their effects. Due to the prevalence of metformin in surface and waste waters, this study investigated its 7 day chronic toxicity. Typically, metformin is prescribed with other medications to control blood sugar levels and achieve healthy HbA1c (hemoglobin) levels for people with type 2 diabetes (T2D).

Methods

Accordingly, the effect of metformin on catfish (Clarias gariepinus) following exposure and post-exposure recovery was evaluated using blood indices as biomarkers for hematotoxicity, electrolytes imbalance, oxidative stress, and immunosuppression. The first group was a control group, the second group was exposed to 10 mg/L of metformin, and the third group was exposed to 50 mg/L of metformin for 7 days, followed by a 15-day recovery period. Hemotoxic effects of the …

Chronic renal failure (CRF) is a progressive loss of renal function that lead to reduced sodium filtration and inappropriate suppression of tubular reabsorption that ultimately leads to volume expansion. The aim of this study was to study the efficacy of furosemide and tadalafil nanoforms compared to conventional forms against adenine-induced CRF rat-model. Addition of 0.75% adenine to the diet of rats for 4 weeks gained general acceptance as a model to study kidney damage as this intervention mimicked most of the structural and functional changes seen in human chronic kidney disease Urine analysis, histopathological changes and immunohistochemical expression of caspase-3 and interleukin-1 beta (IL-1β) in renal tissues were performed. Our results showed that the combination of tadalafil and furosemide using conventional and nanoparticle formulations had better renoprotective effect than individual drugs. This was demonstrated by improvement of urinary, serum and renal tissue markers as indicative of organ damage. This was also reflected on the reduction of tubular expression of kidney injury molecule-1 (KIM-1) and neutrophil gelatinase-associated lipocalin (NGAL). Immunohistochemical studies showed that the deteriorated renal cellular changes indicated by increased expression of caspase-3 and IL-1β were greatly improved by the combined treatment particularly with the nanoforms. The nanoforms of both furosemide and tadalafil had greater renopreventive effects compared with conventional forms against adenine-induced CRF in rats.

Background:   The scope of using controlled intra-vaginal drug releasers (CIDR) in the camel industry was small relative to that of cow, sheep, and goat.
Aim: The purpose of this study was to determine the effects of intramuscular injection of AD3E (25 ml/400 kg) as a premedication protocol before CIDR treatment on ovarian hormones profile and calving rate in dromedary she-camels (Camelus dromedarius) through measuring concentrations of progesterone (P4) and estradiol (E2) before, during, and after CIDR use.
Methods: The study was conducted on she-camels (C. dromedarius) (n = 24) aged between 6 and 14 years. The animals were assigned into two equal groups: CIDR treated group (CIDRgr) and AD3E plus CIDR treated group (CIDR+gr).
Results: Except for hemoglobin, the clinical and hematological findings showed no remarkable change either within each independent group or between CIDRgr and CIDR+gr. Serum P4 and E2 concentrations differed significantly between the first 7 days (during CIDR use) and days from 9 to 15 (after CIDR use) in dromedary camels. Serum concentrations of P4 and E2 showed significant elevation at CIDR+gr at day 0 compared with CIDRgr. This significant increase in serum of P4 and E2 at CIDR+gr compared to those of CIDRgr was also observed either during CIDR use (days 3, 5, and 7) or after CIDR use (days 9, 11, 13, and 15). During CIDR use, serum concentrations of P4 were negatively correlated with those of E2 either in CIDRgr or CIDR+gr, however, they were positively correlated after CIDR removal either in CIDRgror CIDR+gr. Regarding the calving rate, it was highest in CIDR+gr whereas CIDRgr showed the lowest one.
Conclusion: It was concluded that the AD3E pretreatment protocol of she-camels before insertion of CIDR could be used successfully during the breeding season to improve fertility in she-camels whereas the serum ovarian hormones profile and calving rates were clearly changed due to pretreatment of she-camels with AD3E before CIDR insertion.
