Objectives: To evaluate anti-psoriatic activity of Phytochemicals on UV-Induced psoriasis in mouse tail model. Materials and Methods: Anti-psoriatic activity of selected phytochemicals on UV-Induced psoriasis in mouse tail model. The animals were dividing into 05 groups and each group contain 5 animals. Disease control group did not receive any treatment only exposure to UV-light, vehicle control treated with simple ointment, standard group treated with salicylic acid (1%w/w) ointment, remaining group are treated 1% and 2% selective phytochemical at two concentrations of ointment to topically on the tail skin. And the data were analysed using one way ANOVA followed by two-way ANOVA (Dunnett’s multiple comparisons test). Results: There was significant decrease in epidermal thickness (P < 0.05) as compared with control group. In 2% phytoconstituents has shown a significant reduction in the total epidermal thickness 8.4****±0.748, 7.6**±0.6781 and 8*±0.8366 in geraniol, glycyrrhizic acid and ellagic acid treated group, when compare to the disease induced animal, there was no lesion of Munro’s microabscess, capillary loop dilation along with elongation of rete ridges in the section of skin of rats. Psoriasis Severity Index was reduced in test treated groups as compared with that of disease control group. It was slowly reduced to 2nd week, totally (55-70%) reduction in PSI is observed at the time of third week of treatment period. Conclusion: The result of the study showed that the 2% of geraniol, ellagic acid, glycyrrhizicacid and hesperidin, exhibited significant activity on UV-induced psoriasis in rodents. The study implies that selected phytoconstituents are a promising research for further investigations to prove its anti-psoriatic activity.

Objective To determine the association between serum visfatin levels and psoriasis and to evaluate the correlation between serum visfatin levels and the severity of psoriasis. Methods The electronic databases PubMed®, Embase® and the Cochrane Library were searched for articles published from inception to 1 May 2020. Data were extracted and then standard mean differences (SMDs) and 95% confidence intervals (CIs) were calculated for pooled estimates. Results A total of 11 studies met the inclusion criteria and were included (448 patients diagnosed with psoriasis and 377 controls). This meta-analysis demonstrated that patients with psoriasis had significantly higher levels of visfatin than the controls (SMD = 0.90, 95% CI 0.52, 1.28). Subgroup analyses showed that differences in serum visfatin levels between the patient group and the control group were associated with ethnicity, Psoriasis Area and Severity Index (PASI) and body mass index. Additionally, a meta-analysis of correlations showed that visfatin levels in patients with psoriasis were positively correlated with PASI ( r = 0.51, 95% CI 0.14, 0.75). Conclusions This meta-analysis showed that serum visfatin levels in patients with psoriasis were significantly higher than those in the controls and a positive correlation between serum visfatin levels and psoriasis severity was observed.

AbstractCold atmospheric plasma (CAP) has been incorporated into various fields, including promotion of cutaneous wound healing. Atopic dermatitis (AD) is a chronic cutaneous condition characterized by inflammation-induced skin wounds and impaired skin barrier function. To investigate whether CAP may improve AD using an animal model. Dermatophagoides farinae extracts (DFE)-induced murine models of AD were used in this study. The plasma-treated group received a total of 6 CAP treatments during 2 weeks, while the control group did not receive any treatment. Differences in dermatitis severity, transepidermal water loss (TEWL), serum level of immunoglobulin (Ig) E and epidermal thickness were evaluated in both groups. The dermatitis severity was significantly improved by CAP treatment. TEWL was lower in the plasma-treated group compared with the non-treated control group. Serum Ig E dropped significantly after treatment with CAP. Difference in epidermal thickness of the ear skin was not significant between the plasma-treated and non-treated groups. Localized treatment of AD with CAP decreases dermatitis severity, TEWL, and serum Ig E level. These results show CAP’s potentials as a novel therapeutic modality for AD.

The aim of the study was to evaluate concentrations of IL-17 in the serum and plaque scales of psoriatic patients. We analyzed their association with the clinical activity of the disease and with body mass index (BMI). Demographic data, medical history, serum, and scale from psoriatic plaques for assessment of IL-17 were collected from all the participants. The disease severity was assessed with PASI (Psoriasis Area and Severity Index), BSA (Body Surface Area), PGA (Physician Global Assessment), NAPSI (Nail Psoriasis Severity Index), and DLQI (Dermatology Quality of Life Index) scores. Obesity was diagnosed by calculating body mass index. Serum and scale concentration of IL-17 was determined with Human IL-17A High Sensitivity ELISA kit and Human IL-17 ELISA kit. In the psoriatic patients, BMI was statistically significantly higher than in the control group. Most of the patients presented BMI higher than normal. Our study confirms that overweight is a problem among psoriatic patients. A significant positive correlation between the IL-17 serum and scale concentrations and psoriasis severity indicates that IL-17 can be used as the marker of disease severity. More data from human studies can be crucial for understanding that relationship between IL-17, psoriasis, and obesity.

Objective: The current study was designed to evaluate the protective effect of standardized hydroalcoholic extract of Plumeria rubra (HAEPR) against cisplatin-induced nephrotoxicity in Wistar rats.  Methods: HAEPR was administered orally at 3 dose levels (100,200,400 mg/kg). Vitamin E (250 mg/kg) was used as a Standard nephroprotective agent. The kidney function test (estimation of serum creatinine, albumin, blood urea nitrogen) oxidative stress study (estimation of superoxide dismutase, malondialdehyde activity) and histological examination of kidneys was conducted. Results: The efficacy of HAEPR was compared with Cisplatin (CP) treated group. Serum creatinine and BUN was significantly (p<0.01) elevated in CP-treated group compared to the control group. HAEPR (100,200 mg/kg) and Vitamin E (250 mg/kg) significantly (p<0.01) decreased the serum creatinine and BUN levels. CP treated group exhibited significant (p<0.01) decrease in albumin when compared to control. Significant (p<0.01) increase in the serum albumin level was found in HAEPR (100,200 mg/kg) and Vitamin E (250 mg/kg) compared to CP group. Significant (p<0.01) decrease in the activity of SOD was observed in the CP group as compared to control. HAEPR (100 and 200 mg/kg) and Vitamin E (250 mg/kg) significantly (p<0.01) increased SOD levels. HAEPR (400 mg/kg) significantly (p<0.05) increased SOD levels. HAEPR (100,200,400 mg/kg) significantly (p<0.01) decreased MDA levels as compared to CP group. Histopathological examination of the kidneys showed that HAEPR markedly ameliorated Cisplatin-induced renal tubular necrosis. An extract was found effective at all doses, although low dose (100 mg/kg) was found to be more effective and comparable with the standard group (Vitamin E 250 mg/kg).  Conclusion: Present investigation revealed that HAEPR resulted in attenuation of Cisplatin-induced renal damage in rats.

Background: This study aims to evaluate the per se effect of piperine and its interaction with ondansetron on haloperidol induced catalepsy in swiss albino mice.Methods: The piperine crystals were separated from crude extract of Piper nigrum. Catalepsy was induced by haloperidol (1mg/kg, i.p.). Control group received 2% gum acacia (10ml/kg), standard group ondansetron (0.5mg/kg), test group piperine (10mg/kg) and combination group ondansetron plus piperine (0.5mg/kg + 10mg/kg), per oral, respectively. In acute study, drugs were administered only once, one hour prior to the haloperidol administration. Whereas in chronic study, catalepsy was determined on the seventh day of treatment.Results: In acute study, from 60 min onwards after haloperidol administration, ondansetron and ondansetron plus piperine group resulted in significantly lower cataleptic scores than the control treated group. On the other hand, 120 min onwards ondansetron group showed significantly lower cataleptic scores (24.62) as compared to the ondansetron plus piperine group (31.50). In the chronic study, from 60 min onwards, ondansetron and the ondansetron plus piperine resulted in significantly lower cataleptic scores than the control treated group. Also the combination of ondansetron plus piperine was more significantly protective compared to ondansetron alone (P <0.05).Conclusions: Piperine has the potential to be used as a bioenhancer when combined with other drugs which would reduce the dose of drugs and thereby adverse effects. It may act probably by enhancing the bioavailability as well as by inhibiting the metabolic pathways of other drugs.

Background. Goeckerman’s therapy (GT) of psoriasis is based on daily application of pharmacy grade coal tar on affected skin with subsequent exposure to UV light. Disturbances in angiogenic activity are characteristic for the immunopathogenesis of psoriasis. The aim of study was to evaluate the influence of GT of psoriasis on proinflammatory and angiogenic activities expressed as changes in levels of endoglin (CD105). Methods. Serum levels of a soluble form of endoglin were measured in peripheral blood samples of 38 patients with psoriasis before and after therapy. Sixty three otherwise healthy blood donors serve as a control group. The efficacy of GT was expressed as changes in Psoriasis Area and Severity Index (PASI). Results. PASI score was significantly diminished by GT (p<0.001). Serum levels of soluble CD105 were significantly diminished after GT. The serum level of soluble CD105 dropped from 7.85 ± 2.26 ng/ml before therapy to 7.01 ± 1.71 ng/ml after therapy (p= 0.0002). Compared to serum levels of soluble CD105 in healthy blood donors, serum levels of soluble CD105 in patients before GT were significantly higher (p<0.001) and remained elevated after therapy (p<0.001). Angiogenic activity expressed as serum endoglin is diminished in patients with psoriasis treated by GT.

To determine the effectiveness of both topically applied Betamethasone valerate and Calcipotriol ointments for the therapy of mild and moderate types of psoriasis. This comparative study was conducted in Jinnah Postgraduate Medical Centre, Karachi in the Pharmacology and Therapeutics department of BasicMedical Science Institute (BMSI). In 90 days study, 80 patients of mild and moderate psoriasis vulgaris were placed into A and B groups. The Betamethasone valerate treated patients were placed in group A while Calcipotriol treated patients were placed in group B; 40 patients in each group. The Psoriasis AreaSeverity Index (PASI criterion) was used to observe improvement in psoriatic patients taking these drugs. In this randomized and comparative study, psoriasis severity was checked by Psoriasis Area Severity Index (PASI). At day 90 Calcipotriol treated group B patients showed more improvement in mean PASI score ascompared to Betamethasone valerate treated group A patients. In PASI score, Calcipotriol shows 71.61% betterment whereas Betamethasone vale rate shows 63.2% betterment in mild psoriatic patients. In PASI score, Calcipotriol shows 69.21% betterment whereas Betamethasone valerate shows 60.44% betterment inmoderate psoriatic patients. In Pakistani population topically applied Calcipotriol ointment was more efficacious in the treatment of mild and moderate types of psoriasisvulgaris when compared to topically applied Betamethasone valerate ointment.
