 This study was aimed to displayed effect of this nanoparticles on pregnant mother and embryos. All females administration of AgNPs suspension orally during the gestational period (for 21day) in two doses low 2mg and high dose 20 mg /Kg body weight and the control group received D.W only. The pregnant females (60 females) include the control group and the treated group  was subdivided in to two groups, pre and post implantation and all the mothers weighted along the study. The embryos and their brains after retrieved weighted and the crow-rump length (CRL) measurement also. The results showed that the active form of Ag can be transport the placental barrier and blood brain barrier (BBB). This nanoparticles showed adverse effect and produced decreased in mothers weights in low dose 2mg/Kg/ B.Wt and higher dose 20mg/Kg/ B.Wt. Weights of embryos were lower clearly after exposure to AgNPs compare to control group. On the other hand, the weights of embryo's brain were decreased compare of control group in both doses. The CRL of embryos lowered after exposure to AgNPs in treatment groups when compare to control group.

In this study, we evaluated the inflammatory responses induced by aluminum silicate (AS) cytotoxicity in rat lungs. The prophylactic effect of propolis extract was evaluated in 60 adult male albino rats. The rats were divided into six groups: (1) a normal, healthy control group; (2) a normal group fed with 200 mL of propolis extract/Kg; (3) a low-dose positive control group injected with 5 mg/kg of AS; (4) a treated group given propolis and a low dose of AS; (5) a high-dose positive control group injected with 20 mg/kg of AS; and (6) a treated group given propolis with a high-dose of AS. At the end of the two-month experiment, the rats’ lungs were removed. For each pair of lungs, one portion was subjected to biochemical analysis and the other underwent hematoxylin and eosin (H&E) staining in order to study its histology. The rats that received AS doses displayed significant disorders in their antioxidant contents as well as in their enzymatic activities and their histopathological structures revealed severe damage to their lung tissues. Upon the rats being treated with propolis, the enzymatic and antioxidant contents improved and partial improvements in the lung structures appeared, including minimized congestion, a reduced hemorrhage of blood vessels and preserved bronchioles, alveolar ducts, and alveoli. The prophylactic effectiveness of propolis extract on the cytotoxicity of AS, owing to the antioxidant properties of propolis, were studied.

The antioxidant protective effects of fruit juice of cucumber and watermelon on lipid profile of cadmium induced toxicity on male albino rats was investigated. Forty male rats were divided into eight groups. Group NC served as normal control group while group PC was positive control that was not treated but induced with cadmium. Groups I to VI received high dose and low dose of juice of Cucumber and Watermelon respectively. Excluding the normal control group, other groups were fed with lard 14 days before treatment commenced.  Doses of 0.8 mg/kg-high dose and 0.4 mg/kg-low dose for cucumber and watermelon respectively. At the 4th and 6th week, biochemical parameters were assayed. Results revealed that the levels of total cholesterol, LDL, VLDL and triglyceride significantly (P˂0.05) were decreased compared to positive control but HDL was increased in treatment groups compared to positive control. Pretreatment with cucumber and watermelon juice indicated that total cholesterol, LDL, VLDL and triglyceride significantly (P˂0.05) were decreased compared to positive control but HDL was increased in treatment groups compared to positive control. The result also revealed an increase in testosterone levels in treated groups after 4 weeks of administration of whole extract of cucumber and watermelon when compared to their week 2 values. Testosterone level in positive control was also reduced significantly from 1.5±0.14 ng/ml to 0.46±0.31 ng/ml. Histological evaluation of the testes of normal control group revealed that the interstitium was intact with leydig cells present and maturing germ cells embedded in normal seminiferous tubules while the other groups that were induced with cadmium only showed morphology of testes with empty seminiferous tubules and consolidated interstitial spaces.

We investigated the effect of Panax ginseng extract, which is rich in the ginsenoside protopanaxatriol (Ginseol K-g1), on blood pressure (BP). Adults over 20 years old with a systolic BP (SBP) between 120 and 159 mm Hg or a diastolic BP (DBP) between 80 and 99 mm Hg were included. At the end of an initial 2-week washout period, the patients were divided into three groups: the control group (placebo), the low-dose Ginseol K-g1 group (100 mg), and the high-dose Ginseol K-g1 (300 mg) group. The primary end point was the difference in seated SBP (seSBP) and seated DBP (seDBP) changes between the placebo and Ginseol K-g1 groups after 8 weeks of treatment. A total of 90 subjects participated in the study (mean age; 55.2 ± 11.8 years, 43 males). At week 8, levels of seSBP and seDBP were significantly decreased from baseline in the high-dose Ginseol K-g1 group (-3.1 mm Hg and -2.3 mm Hg, respectively, p < 0.05). In contrast, there was no significant decrease in seSBP or seDBP in the control or low-dose Ginseol K-g1 groups. No significant difference of seSBP and seDBP was identified among the three treatment groups at week 8. In patients who had a seSBP ≥ 130 mm Hg or an seDBP ≥ 85 mm Hg, the high dose of Ginseol K-g1 decreased the BP compared with the control group at week 4; however, there was no significant difference at week 8. The proportions of patients who experienced adverse events were comparable among the treatment groups. In conclusion, Ginseol K-g1 has a favorable effect on BP after 4 weeks of treatment, especially at a high dose. However, the effect is not maintained over 8 weeks.

Lactobacillus plantarum BW2013 was isolated from the fermented Chinese cabbage. This study aimed to test the effect of this strain on the gut microbiota in BALB/c mice by 16S rRNA amplicon sequencing. The mice were randomly allocated to the control group and three treatment groups of L. plantarum BW2013 (a low-dose group of 108 CFU/ml, a medium-dose group of 109 CFU/ml, and a high-dose group of 1010 CFU/ml). The weight of mice was recorded once a week, and the fecal samples were collected for 16S rRNA amplicon sequencing after 28 days of continuous treatment. Compared with the control group, the body weight gain in the treatment groups was not significant. The 16S rRNA amplicon sequencing analysis showed that both the Chao1 and ACE indexes increased slightly in the medium-dose group compared to the control group, but the difference was not significant. Based on PCoA results, there was no significant difference in β diversity between the treatment groups. Compared to the control group, the abundance of Bacteroidetes increased in the low-dose group. The abundance of Firmicutes increased in the medium-dose group. At the genus level, the abundance of Alloprevotella increased in the low-dose group compared to the control group. The increased abundance of Ruminococcaceae and decreased abundance of Candidatus_Saccharimonas was observed in the medium-dose group. Additionally, the abundance of Bacteroides increased, and Alistipes and Candidatus_Saccharimonas decreased in the high-dose group. These results indicated that L. plantarum BW2013 could ameliorate gut microbiota composition, but its effects vary with the dose.

Background The aim of this study was to compare the effect of antileukotriene (anti-LT), antihistamine, and a combination of anti-LT and antihistamine on the symptoms and nasal resistance in allergic rhinitis patients. Methods We performed a placebo-controlled study, with 120 persistent, moderate to severe allergic rhinitis patients randomly selected to receive the different treatments for 4 weeks: no treatment, 10 mg of cetirizine once per day, 20 mg of zafirlukast once per day, 20 mg of zafirlukast twice per day, a combination of 20 mg of zafirlukast and 10 mg of cetirizine once per day, or a combination of 20 mg of zafirlukast twice per day and 10 mg cetirizine once per day. The nasal secretion nitric oxide (NO) concentration, nasal symptom score, and nasal resistance were measured before and after treatment. Results Total symptom scores improved in each treated group compared with the control group (p < 0.05). Nasal obstruction significantly improved in the anti-LT-treated groups (p < 0.05). High-dose anti-LT or the combination of low-dose anti-LT and antihistamine significantly improved allergy symptoms compared with no treatment, low-dose anti-LT, or antihistamine alone (p < 0.05). Furthermore, anti-LT decreased NO concentration in nasal secretions (p < 0.05), regardless of the dose administered. Conclusion These results suggest that high-dose anti-LT alone or the combination of low-dose anti-LY and antihistamine can effectively treat allergic rhinitis.

This work was conducted on six groups of day-old Cobb-400 broiler chicks to study the ameliorative effect of febuxostat on gout induced model. Clinical signs were noticed in birds of diclofenac control group II and low dose febuxostat treated group IV. During the study, 27.77% and 22.22% mortality were observed in diclofenac control group II and low dose febuxostat treated group IV, respectively. Febuxostat control group III and febuxostat (medium and high dose) treated groups V and VI had no mortality. Reduction in body weight gain and feed intake was observed in diclofenac control group II as compared to without treatment control group I at the end of every week during the experimental period of 21 days. Reduction in body weight gain and feed intake was observed in low dose febuxostat treated group IV as compared to control group at the end of 1st week. The average FCR was higher in diclofenac control group II (2.54) and low dose febuxostat treated group IV (2.14) as compared to control group (2.00). Kidney: body weight ratio was significantly high in diclofenac control group II as compared to control group at the end of experiment. Gross and microscopic lesions of visceral gout were mainly observed in chicks that died during the experiment from diclofenac control group II and low dose febuxostat treated group IV. The overall lesions showed that diclofenac was nephrotoxic and hepatotoxic in nature. Febuxostat at lower than the therapeutic dose did not prevent nephrotoxicity and hepatotoxicity caused by diclofenac leading to visceral gout. Febuxostat control III and febuxostat (medium and high dose) treated groups V and VI did not reveal any pathomorphological changes. Judicious use of febuxostat is safe in poultry birds between the limit of 4 mg/kg and 6 mg/kg

Aim: To ascertain early detection of possible kidney injuries in albino rats exposed to formaldehyde by assessing cystatin C, serum electrolytes, urea and creatinine. Materials/Methods: Thirty healthy adult male albino rats, weighing between 100 to 120 grams were randomly divided into three groups A, B and C. Group A served as control. Group B was exposed to low dose (100ppm of Formaldehyde), 3 hrs per day for four weeks, while group C was exposed to high Dose-200ppm of formaldehyde 3 hrs per day for four weeks. At the end of the exposure period, the rats were sacrificed by decapitation under chloroform anesthesia, and 4 ml of blood samples was collected from each rat into a plain bottle. The whole blood was allowed to clot, retracted and centrifuged at 3000 rpm for 10 minutes and serum separated. The serum was stored at -20˚C until analyses for serum electrolytes, creatinine and cystatin C. Serum electrolytes were determined using Ion selective electrode, urea and creatinine were determined using spectrophotometric methods while cystatin C was analyzed using Eliza. Data obtained was analyzed using SPSS. Results: The concentrations of the serum electrolytes, sodium. Potassium, bicarbonate and chloride were compared across the three group, they were not statistically significant (p>0.05). Urea was significantly higher in group C when compared with low dose B and control group A (P<0.05). Also, when the low dose group B was compared with the high dose group C, it was statistically significant. Creatinine concentrations were significantly higher in group C when compared with the control group A, while group B was not significant when compared with group A. Finally, the cystatin C concentrations were also significant when groups B, C were compared with the control group. Conclusion: Formaldehyde exposures may induce a gradual deterioration of renal functions in chronically exposed albino rats. Serum electrolytes, urea and creatinine may not be sufficient to indicate an early signs of kidney damage. From the study, serum cystatin C may be a better marker of renal impairment in early stages.

This study evaluated camphora-induced androgenic and histopathological changes in male Sprague-Dawley rats. Thirty-five animals weighing 200 g±20 g were used for this study and randomly divided equally into five groups, with seven rats in each group. Group A animals (normal control group) were served water and rat chow only; Groups B-D (treatment groups) were orally administered camphora in doses of 1 g/kg (Low-dose), 2 g/kg (Medium-dose) and 4 g/kg (High-dose) respectively while Group E (vehicle group) were orally administered 6 mL/kg olive oil (a solvent for camphora) per day for 56 days. There was a significant decrease (P< .05) in activity levels of Follicle-Stimulating Hormone (FSH); Superoxide Dismutase (SOD) when the treatment was compared with the control group. Also, a significant decrease (P< .05) in activity level of FSH was observed when the Medium-dose group was compared with Low-dose group. Insignificant irregular pattern in activity level of Testosterone was observed across the treatment groups when compared with the control. However, a significant increase (P< .05) in activity level of Testosterone was observed when the High-dose group was compared with the Medium-dose group. There was a significant increase (P< .05) in activity levels of Luteinizing Hormone (LH) and Malondialdehyde (MDA) when the treatment was compared with the control group. Semen analysis showed reduction in sperm concentration, motility and morphology with increasing concentration of camphora. Significant decrease was recorded in testicular weight when High-dose group was compared to Control and Low-dose groups. Histopathological changes were seen in the testes of the camphor administered groups, ranging from mild disintegrated interstitial tissues in Low-dose to severe degeneration and disintegration of both seminiferous and interstitial tissues in the testes in the Medium-dose and High-dose groups. In conclusion, camphora had androgenic and toxic effects on testis and may cause testicular tissue damage.

Abstract: Drug-induced liver injury (DILI) is an adverse drug reaction which vary in its clinical manifestations, ranging from an asymptomatic increase in liver enzymes to fulminant hepatic failure. Several drugs can cause DILI, one of which is corticosteroid. Methylprednisolone (MT) is a kind of corticosteroid drug which is considered to be a safe drug and it is not believed to cause DILI and often used for the treatment of severe hepatitis. However, there are some reports of DILI in patients treated with high-dose MT. The objectives of this study was to determine the effect of oral administration of MT on liver’s histological changes of witar rats. This study was using 15 rats which were divided into 3 groups; 1 negative control group (group A) and 2 treatment groups (group B and group C). Group B was given a low-dose oral MT, 2 mg/day, while group C was given oral high-dose MT, 4 mg/day for 14 consecutive days. The results showed steatohepatitis features in both low-dose and high-dose MT administration groups. Histopathological features of both treatment groups are similar. Qualitatively, high-dose MT group showed worse histopathological features than the low-dose MT group. Conclusion: Administration of MT by 2mg/day and 4mg/day may induced steatohepatitis in wistar rat’s liver.Keywords: methylprednisolone, liver histopathological features Abstrak: Drug-induced liver injury (DILI) atau cedera hati akibat obat merupakan reaksi efek samping obat dengan manifestasi klinis yang beragam, mulai dari peningkatan enzim-enzim hati yang bersifat asimptomatik sampai dengan timbulnya gagal hati fulminan. Banyak obat-obatan yang dapat menyebabkan DILI, salah satunya adalah golongan kortikosteroid. Metilprednisolon (MT) adalah obat golongan kortikosteroid yang dianggap sebagai obat yang aman dan tidak diyakini dapat menyebabkan DILI, bahkan sering digunakan untuk terapi pasien hepatitis berat. Akan tetapi, beberapa klinisi melaporkan kasus DILI pada pasien-pasien yang diterapi dengan MT dosis tinggi. Penelitian ini bertujuan untuk mengetahui efek pemberian MT oral terhadap perubahan histologik hati tikus wistar. Jenis penelitian yang dilakukan adalah eksperimental laboratorik menggunakan 15 ekor tikus yang dibagi dalam 3 kelompok; 1 kelompok kontrol negatif (kelompok A) dan 2 kelompok perlakuan (kelompok B dan kelompok C). Kelompok B diberikan MT oral dosis rendah sebanyak 2 mg/hari sedangkan kelompok C diberikan MT oral dosis tinggi sebanyak 4 mg/hari setiap hari selama 14 hari berturut-turut. Hasil penelitian menunjukkan gambaran yang sama secara mikroskopik pada kedua kelompok perlakuan yaitu terjadinya steatohepatitis. Tetapi secara kualitatif, kelompok tikus yang mendapatkan MT dosis tinggi memberikan gambaran histopatologik yang lebih jelek dibandingkan kelompok yang diberi dosis rendah. Simpulan: Pemberian metilprednisolon dosis 2mg/hari dan dosis 4 mg/hari dapat mencetuskan terjadinya steatohepatitis pada hati tikus wistar. Kata kunci: metilprednisolon, gambaran histopatologik hati
