<p>Chemotherapy-induced alopecia affects the pathological as well as the psychological aspects of the cancer patient. In the present study, the protective role of Nigella sativa was evaluated in both adult and newborn albino rats. The anagen phase was first induced. N. sativa oil, N. sativa decoction (5%, 10% and 15%) and minoxidil lotion (standard) were applied daily to the rats two days after the depilation. During the anagen VI phase of the hair follicles, alopecia was induced by giving cyclophosphamide 125 mg/kg, ip to the adult rat and 50 mg/kg to the newborn rats. Cyclophosphamide-induced the alopecia to the whole depilated area of skin in adult rat while alopecia totalis was observed in the newborn rat disease control group. N. sativa oil, N. sativa decoction (5%) showed a significant protective effect against cyclophosphamide-induced alopecia. In conclusion, it is evident that N. sativa provides significant protection against chemotherapy-induced alopecia.</p><p><strong>Video Clip of Methodology</strong>:</p><p>1 min 43 sec:   <a href="https://www.youtube.com/v/AKhk27V3juE">Full Screen</a>   <a href="https://www.youtube.com/watch?v=AKhk27V3juE">Alternate</a></p>

Aim: In cyclosporin-A (CsA)-induced toxicity, oxidative stress has been implicated as a potential responsible mechanism. Therefore, we aimed to investigate the protective role of erdosteine against CsA-induced nephrotoxicity in terms of tissue oxidant/antioxidant parameters and light microscopy in rats. Materials and methods: Wistar albino rats were randomly separated into four groups. Group 1 rats treated with sodium chloride served as the control, group 2 rats were treated with CsA, group 3 with CsA plus erdosteine, and group 4 with erdosteine alone. Animals were killed and blood samples were analyzed for blood urea nitrogen (BUN), serum creatinine (Cr), uric acid (UA), total protein (TP), and albumin (ALB) levels. Kidney sections were analyzed for malondialdehyde (MDA) and nitric oxide (NO) levels and superoxide dismutase (SOD), catalase (CAT), and glutathione peroxidase (GSH-Px) activities, as well as for histopathological changes. Results: In the CsA group, MDA, GSH-Px, BUN, and Cr levels were increased. The TP and ALB levels were decreased. These changes had been improved by erdosteine administration. Other biochemical parameters did not show any significant change. Conclusion: These results indicate that erdosteine produces a protective mechanism against CsA-induced nephrotoxicity and suggest a role of oxidative stress in pathogenesis.

Abstract Introduction: Prolonged breathing of high oxygen concentration leads to hyperoxic acute lung injury. Neonatal Respiratory diseases usually require increased supplement of high oxygen concentrations, so neonates are more susceptible to hyperoxic acute lung injury. The aim of this work was to investigate the protective role of caffeine versus N-acetylcysteine against hyperoxic acute lung injury in neonatal rats. Materials and Methods: 32 albino rats aged seven days were used in this experiment. The pups were divided into four groups; 1) Control or normoxic group; rats placed in normoxic chamber where fraction of inspired oxygen (FiO2) was 0.21, 2) Hyperoxic group; rats were placed in hyperoxic chamber (FiO2>0.8) using an oxygen flow of 1.5 Litre/min, 3) Hyperoxia-CAF group; rats exposed to hyperoxia and received a single intra-peritoneal injection of 20 mg/kg caffeine just prior to exposure, and 4) Hyperoxia-NAC group; rats exposed to hyperoxia and received a single intra-peritoneal injection of 150 mg/kg N-acetylcysteine just prior to exposure. 48 hours after exposure, lung specimens were processed for histological and immunohistochemical study using caspase-3, cluster of differentiation-68-antibody (CD68) and interleukin-1-beta (IL-1β). Results: Neonatal hyperoxia led to severe impairment in lung architecture, with a highly significant increase in alveolar macrophages. Also, caspase and IL-1β immune-reaction were increased significantly as compared to control group. Caffeine could improve the histolopathological picture of hyperoxic acute lung injury, and also could decrease alveolar macrophage count and IL-1β immune-reaction better than N-acetylcysteine. Conclusion: Caffeine is more effective than N-acetylcysteine in prophylaxis against hyperoxic acute lung injury in neonates.

Introduction: In the study, it was aimed to investigate the possible protective effects of curcumin, a potent antioxidant, against the toxic effect of nonylphenol on bone development. Methods: Thirty pregnant female Wistar albino rats were used. The rats were randomly divided into the following five groups; the control group, corn oil group (150 µl/kg/day), nonylphenol group (50 µl/kg/day), curcumin group (100 mg/kg/day) and curcumin + nonylphenol group (100 mg/kg/day + 50 µl/kg/day). The doses were given by gavage from the 5th day to the 20th day of gestation. The fetuses were removed out on the 20th day of pregnancy by cesarean at the end of the study. After the sacrifice of the animals, double skeletal staining in front extremity (clavicula, scapula, humerus, radius, ulna) and hind extremity (femur, tibia, fibula), additionally histological and immunohistochemical examinations in femur bone were performed. Results: The nonylphenol group offspring have the lowest weights of fetuses and placenta, head-to-hip lengths, biparietal and occipitofrontal length, and also, bone length percentage and percentage of the ossification area in all measurements of the front extremity and hind extremity Interestingly, the groups treated with curcumin showed close to the control group in terms of double skeletal staining, histological, and immunohistochemical examinations. Conclusions: Our findings demonstrated an association between bone development and exposure to nonylphenol. The findings suggest that curcumin treatments may be effective in accelerating bone formation.

Objective: Pulmonary fibrosis (PF) is an irreversible and untreatable human disease encompasses a large group of chronic lung disorders associated with excessive remodeling, scarring, and fibrosis. The current work was designed to study the harmful effects of methotrexate (MTX) administration on the lung and the possible protective role of Carthmus tinctorius leaves extract. The animals were utilized in this study. Methods: A total of 40 male healthy adult Wistar albino rats with anaverage body weight of 200±25 g, were divided into four groups (10 animals each). G1: control group, G2: MTX group, G3: Carthamus tinctorius (CT), group G4:MTX+Carthamus tinctorius(CT). CT was administered orally at a dose of (40 mg/kg/day) for 4 w to G3 and G4. The (CT) group were performed to explore any toxic effect of the (CT) extract on the lung. Rats of G2 and G4 administered 4 mg/kg dose of MTX orally for 28 d. Rats of G1 were intraperitoneally (i. p) administered with normal saline 0.5 ml ∕ day for four weeks (4wk) to serveas control. The animals were weighed at the beginning, though, and at the end of experiments. Results: The study showed that the relative lung weight was significantly increased at (P˂0.01) in MTX-treated animals in comparison to the control group. A combination of CT extract with MTX revealed significant decrease (P<0.01) in the lung relative weight in comparison to MTX group. Histopathological examination revealed that lung injury was less severe in group 3 and 4compared to group 2. The results indicated that CT significantly decreased collagen deposition, hydroxyproline content, and ameliorated pathological changes. Conclusion: The study has clearly identified the importance protective role of CT extract on pulmonary fibrosis induced by methoxerate. We recommended CT as one of therapeutic strategy to amelioratethe lung fibrosis associated with methotrexate therapy.
