Background: The safety of the use of medicinal plants is a general challenge among consumers. To improve the use, it is necessary to provide complete profiles of the natural medications for quality control and the therapeutic and toxicity effects. This study was conducted to evaluate the structural and functional toxicity of the methanolic extracts of Salvia rhytidea and Glycine max plants in mice.  Methods: After determining the LD50, NMRI mice with mean weight of 25-30 g were treated intraperitoneally with 100, 200 and 400 mg/kg, and orally with 800 mg/kg of the extracts for 7 consecutive days. After the last treatment, the serum samples were prepared and used for the biochemical assays. The liver and left kidney were removed from the animals and fixed in 10% formalin for histopathological examinations.  Results: The results indicated that the biochemical parameters of liver and kidneys were not significantly different among the experimental and control groups (P>0.05). Mild degenerative changes in the liver and kidneys were observed at the IP dose of 400 mg/kg and oral dose of 800 mg/kg of both extracts.  Conclusion: The use of these plants’ extracts did not induce severe toxicity in the short-term; however, caution should be exercised with the long-term use.

Equine theileriosis, an OIE listed disease caused by Theileria equi is an economically important haemoprotozoan disease of horses in tropical and subtropical parts of the world. The aim of the present study was to monitor the biochemical alterations in order to find out the severity of the disease. Standard assay kits were used to study the biochemical parameters of horses positive for theileriosis in comparison with healthy ones. Out of 75 serum samples, 25 samples were collected from horses positive for theileriosis and 50 from healthy horses. The serum levels of GPT (32.00±2.30 U/L), GOT (350.84±27.87 U/L), GGT (20.95±0.92 U/L), LDH (823.74±102.93 U/L), total protein (8.11±0.37 g/dl), globulin (3.84±0.40 g/dl), BUN (46.26±5.27 mg/dl) and creatinine (1.33±0.18 mg/dl) were found to be significantly increased (p less than 0.01) in infected horses compared to the healthy group. Non- significant elevation (p greater than 0.05) in total bilirubin (1.08±0.14 mg/dl), unconjugated bilirubin (0.57±0.11 mg/dl) and glucose (102.57±30.41 mg/dl) as well as non-significant reduction (p>0.05) in conjugated bilirubin (0.42±0.04 mg/dl), albumin (4.26±0.24 g/ dl) and A/G ratio (1.55±0.30) were also observed in infected group. There was no significant alteration (p>0.05) in the level of serum calcium (12.32±0.36 mg/dl) and phosphorus (4.53±0.33 mg/dl), as compared to the healthy group. Significant elevation of GOT, GPT, GGT, BUN and creatinine revealed the involvement of liver and kidney functions in T. equi infected horses.

It is well known that the rat adrenal zona glomerulosa steroidogenic activity is controlled by the renin-angiotensin system. The ultrastructural changes in the rat zona glomerulosa cells induced by renovascular hypertension were described previously, but as far as we are aware no correlated biochemical and morphometric investigations were performed.Twenty adult male albino rats were divided into 2 experimental groups. One group was subjected to restriction of blood flow to the left kidney by the application of a silver clip about the left renal artery. The other group was sham-operated and served as a control. Renovascular hypertension developed in about 10 days: sistolic blood pressure averaged 165 ± 6. 4 mmHg, whereas it was about 110 ± 3. 8 mmHg in the control animals. The hypertensive and control rats were sacrificed 20 days after the operation. The blood was collected and plasma renin activity was determined by radioimmunological methods. The aldosterone concentration was radioimmunologically assayed both in the plasma and in the homogenate of the left capsular adrenal gland.

BACKGROUND Coronavirus disease (COVID-19) is a budding infectious disease that has affected various countries globally. OBJECTIVE The aim of this study was to analyze the effect of COVID-19 disease on liver and kidney functions and to determine their association with the severity and mortality of disease METHODS A total of 100 confirmed COVID-19 adult patients from Madinah city of Saudi Arabia hospitalized between April 28, and June 30, 2020 were included,and categorized into asymptomatic,mild to moderate and severely ill patients.We analyzed the clinical status of liver and renal functioning in all of the three groups. RESULTS The majority of patients (51%) were diagnosed with mild to moderate disease, 27% of patients were severely ill and 22% of patients were asymptomatic.The liver and renal functional analysis showed that the severity of the COVID-19 patients were significantly associated with the kidney and renal impairments exhibiting higher levels of ALT, AST, Creatinine, Urea levels (P < 0.05). Furthermore, in this study, a novel association is found between high Na and Cl levels with the severely ill COVID-19 patients. CONCLUSIONS We concluded from the present study that a significant percentage of COVID-19 patients continued to have a normal liver and renal function during the course of their disease. Nevertheless, severely ill COVID-19 patients were more prone to have abnormal liver and renal functions. During the course of treatment, the patients had a gradual normalization of their liver and kidney parameters and subsequently achieved a complete normal liver and renal functions upon discharge with no mortality.

Abstract Background S. pneumonia infection presents a significant challenge, accounting for 20–38% of hospital-acquired pneumonia, and the leading cause of community-acquired pneumonia despite availability of effective vaccines. Incidence is highest in children under 2 years, the immunocompromised, and elderly. CDC has reported the emergence of antibiotic resistance in ~30% of cases, adding to risk of morbidity and mortality. Fewer than half of the elderly are vaccinated and vulnerable to infection on admission. Passive immunotherapy as an adjunct to vaccines may improve outcomes in such populations. The objective of this study was to evaluate whether seroprotective response induced with a pneumococcal conjugate vaccine could rapidly yield protective opsonic levels of antibody within anticipated duration of hospitalization. Methods Healthy donors (n=30) were immunized with Prevnar. Blood was drawn on days 0, 3, 7, 10, 14, 21, and 28. Samples were pooled and tested for presence of functional opsonic antibodies recognizing capsular polysaccharides. Clearance mechanism of S. pneumonia was based on antibody recognition to pneumococcal capsular polysaccharide and opsonic titers used as an in vitro surrogate to evaluate the efficacy of vaccine. Results There was little to no opsonic activity against most serotypes on day 0, except for low antibody activity with serotypes 1, 3, 4, and 5. Titers increased, with protective levels achieved by day 10 for most serotypes (except 14 and 18C), peaking at day 14 or after across serotypes (Figures 1 and 2). Average titers rose from log2 titer 2 on day 0 to log2 titer 8 on days 21 and 28. Titers against most serotypes reached log2 10 (titer 1024) or higher. Patients remained susceptible to nosocomial infection for at least 10 days post admission until protective titers are reached. OPK titers (log2 scale) for serum samples on day 0 (pre), day 3, 7, 10, 14, 21, 28, and control for S. pneumoniae serotypes 1, 3, 4, 5, 6A, 6B, 7F, 9V. N=2. OPK titers (log2 scale) for serum samples on day 0 (pre), day 3, 7, 10, 14, 21, 28, and control for S. pneumoniae serotypes 14, 18C, 19A, 19F, and 23F. N=2. Conclusion Patients with no prior history of vaccination (or inability to mount response) with Prevnar or pneumovax remain vulnerable to S. pneumonia infection even if vaccinated on entry, due to delayed kinetics in reaching protective titers. These patients may require prophylactic intervention of hyperimmune Ig with high opsonic titers to S. pneumonia, providing protection until vaccine response elicits protective antibodies.

Apoptotic Effects

Methotrexate (MTX) is frequently used drug in treatment of cancer and autoimmune diseases. Unfortunately, MTX has many side effects including the hepato-renal toxicity. In this study, we hypothesized that Luteolin (Lut) exhibits protective effect against the MTX-induced hepato-renal toxicity. In order to investigate our hypothesis, the experiment was designed to examine the effect of exposure of male rats to MTX (20 mg/kg, i.p., at day 9) alone or together with Lut (50 mg/kg, oral for 14 days) compared to the control rats (received saline). The findings demonstrated that MTX treatment induced significant increases in the liver and kidney functions markers in serum samples including Aspartate transaminase (AST), Alanine transaminase (ALT), creatinine, urea and uric acid. MTX also mediated an oxidative stress expressed by elevated malondialdehyde (MDA) level and decreased level of reduced glutathione (GSH), antioxidant enzyme activities, and downregulation of the Nrf2 gene expression as an antioxidant trigger. Moreover, the inflammatory markers (NF-κB, TNF-α, and IL-1β) were significantly elevated upon MTX treatment. In addition, MTX showed an apoptotic response mediated by elevating the pro-apoptotic (Bax) and lowering the anti-apoptotic (Bcl-2) proteins. All of these changes were confirmed by the observed alterations in the histopathological examination of the hepatic and renal tissues. Lut exposure significantly reversed all the MTX-induced changes in the measured parameters suggesting its potential protective role against the MTX-induced toxicity. Finally, our findings concluded the antioxidative, anti-inflammatory and anti-apoptotic effects of Lut as a mechanism of its protective role against the MTX-induced hepato-renal toxicity in rats.

ABSTRACT Bovine tuberculosis persists as a costly zoonotic disease in numerous countries despite extensive eradication and control efforts. Sequential serum samples obtained from Mycobacterium bovis-infected cattle were evaluated for seroreactivity to mycobacterial antigens. Animals received M. bovis by aerosol, intratonsil, intranasal, or intratracheal inoculation. Assays included the multiantigen print immunoassay for determination of antigen recognition patterns, immunoblot analysis for sensitive kinetic studies, and the VetTB STAT-PAK test, a novel, rapid test based on lateral-flow technology. Responses to MPB83 were detected for all M. bovis-infected animals regardless of the route or strain of M. bovis used for inoculation. Other less commonly recognized antigens included ESAT-6, CFP-10, and MPB70. Responses to MPB83 were detectable as early as 4 weeks after inoculation, were boosted upon injection of purified protein derivatives for skin testing, and persisted throughout the course of each of the four challenge studies. MPB83-specific immunoglobulin M (IgM) was detected prior to MPB83-specific IgG detection; however, early IgM responses rapidly waned, suggesting a benefit of tests that detect both IgM- and IgG-specific antibodies. The VetTB STAT-PAK test detected responses in sera from 60% (15/25) of the animals by 7 weeks after challenge and detected responses in 96% (24/25) of the animals by 18 weeks. These findings demonstrate the potential for new-generation antibody-based tests for the early detection of M. bovis infection in cattle.

Abstract Background To compare the aqueous humor (AH) and the serum clusterin levels of patients with pseudoexfoliation syndrome (PEX), pseudoexfoliation glaucoma (PEXG), and primary open-angle glaucoma (POAG) with each other and with an age- and sex-matched control group. Methods This prospective, cross-sectionalstudy evaluated 92 eyes from 92 adult cases of uncomplicated phacoemulsification and posterior chamber intraocular lens (IOL) implantation. The cases were divided into PEX, PEXG, POAG, and control groups. Serum samples were taken from the antecubital vein just before the surgery, and the AH samples were aspirated at the beginning of the surgery. Kruskal-Wallis H, One-way ANOVA, Mann-Whitney U with Bonferroni correction and Chi-Square tests were used for statistical analysis. Results The serum clusterin levels were the highest in the PEXG group, but no statistically significant differences were observed between the groups (p=0.633). The mean AH clusterin levels were 286.79±29.64 μg/mL in the PEXG group, 263.92±31.70 μg/mL in the PEX group, 272.59±49.71 μg/mL in the POAG group, and 193.50±62.38 μg/mL in the control group (p< 0.001). This came out to be 1.48 times increase for the PEXG group, 1.36 for the PEX group, and 1.41 for the POAG group when compared with the control subjects. Conclusions A higher level of clusterin in the anterior chamber was found to be associated with PEX and PEXG. In addition, a high level of anterior chamber clusterin in POAG, which is a new finding, showed that this molecule might be important not only in pseudoexfoliation, but also other types of glaucoma like POAG.
