ABSTRACT

Background: Consequent to the high prevalence of psychiatric disorders in present day world, their caregivers form an important group in the public health. Research on the physical and psychological well-being of caregivers is being carried worldwide with varied results. Psychological health of these caregivers is usually ignored both by these persons themselves and the health-care providers. The objective of the study was to screen for psychiatric morbidity among caregivers of patients attending a psychiatric hospital in North India, and to study the clinical correlates of the same.Methods: A total of 205 patients and their caregivers were consecutively recruited over a one month period. Sociodemographic and clinical information of patients was obtained either from the hospital records or from the caregiver. Scoring of the patient’s global assessment of functioning (GAF) was done by clinicians. The caregivers were administered a sociodemographic questionnaire, general health questionnaire (GHQ-12) and Zarit Burden interview. The presence of psychiatric morbidity was confirmed by a consultant psychiatrist.Results: Among the caregivers, 32.2% had GHQ scores of 3 and above. Majority of caregivers in this study were females (59.0%) while as majority of the patients were males (61.9%). Factors associated with psychiatric morbidity among caregivers include the high level of subjective burden of care, low level of functioning, and comorbid medical and psychiatric conditions.Conclusions: The study reveals a high level of psychiatric morbidity among the caregivers of patients with mental health problems.

ABSTRACT

The effects of Lipidium meyenii [maca, LM] and Epimidium sagittatum [horny goat weed, ES] have been investigated due to their involvement in fertilization. Both of the drugs showed good results before, during and after fertilization in male and female mice. The results revealed that the crude extract of Lipidium meyenii caused a significant decrease in the no. of writhes at 300 and 500mg/kg [p<0.05] as compare to control, Epimidium sagittatum and standard drug. The gross behavioral, open field, exploratory behaviour, forced swimming test for stress, diuretic activity, chronic toxicity with the effect on reproduction of both male and female and change in body weight were also studied. The phytochemical study showed the presence of tannin, alkaloid, carbohydrate, rich protein and absence of sterol in LM, whereas ES shows presence of sterol and less protein. LS improve in muscle activity and exploratory behaviours without any toxic effects on mice and their pups. It does not have diuretic effect for first two hour but act normally after initial phase of drug therapy. Epimidium sagittatum has dual action that is at low dose it has slight stimulation action and at high dose little depressive effect. ES also has some diuretic effect. Overall these results suggest that LM is highly effective remedy for treatment of impotency and reduces stress and depression, because of dual effect ES not only suggested as an anxiolytic medicine but also effective in female hormonal disorder

ABSTRACT

Traditionally Berberis species have been used as anti-inflammatory, anti-rheumatic, analgesic and anti-anemic drugs. This study was aimed to determine chemical constituents and to assess analgesic, anti-inflammatory and hematological effects of the crude extract of the berries of Berberis baluchistanica to verify these folkloric claims. Phytochemical screening, carried out by using different chemical reagents and techniques like Thin Layer Chromatography [TLC] and Fourier Transform Infra-Red [FTIR] indicated presence of flavonoids, saponins, phytosterols and carbohydrates including reducing sugars. Analgesic and anti-inflammatory activities were assessed on mice by using acetic acid induced writhing method and formalin method. Potent anti-inflammatory and analgesic effects were observed during these experiments. The extract also showed anti anemic effect as it increased the levels of hemoglobin and red blood cells significantly. Increase in the platelet count was also noted. The extract of the berries was used at oral doses of 300 and 500 mg/kg during experiments. Anti-inflammatory and analgesic activities were determined by comparing with the standard i.e. aspirin 300 mg/kg. Both doses produced significant anti-inflammatory and analgesic activities at P-0.05. These activities were seemingly attributable to flavonoid and saponin contents of the drug. These results justify the folkloric claims that the drug could be used as good anti-inflammatory, antirehumatic, analgesic and anti-anemic drug. However, further chemical investigations on the drug are suggested for isolation and identification of compounds that could be safer and more effective than the currently available medicines in treating these disorders

ABSTRACT

Present study was conducted on crude methanolic extract of stem and root of Taverniera glabra. In Pakistan T. glabra is found in the region of Balochistan only. T. glabra has numerous therapeutic uses in traditional medicine and it is also used for the pain relief. Current study was carried out to evaluate acute toxicity, analgesic and CNS depressant activity of the plant. Acute toxicity was carried out by oral administration of the T. glabra extract from 250 to 2000mg/kg oral dose. Analgesic activity was carried out by acetic acid induced writhing test and formalin test. Central Nervous System [CNS] depressant activity was carried out by exploratory activities [open field activity, cage crossing activity, rearing test] and forced swimming test. Oral administration of the methanolic extract of T. glabra was nontoxic at the dose of 1500mg/kg in the acute toxicity test. Exploratory behavior of mice treated with the methanolic extract of T. glabra showed sedative effects [P<0.05] in open field, cage crossing, traction and rearing test, particularly at the dose of 500mg as compared with standard drug Diazepam. In forced swimming test, mobility time was significantly [P<0.05] increased at 500mg/kg oral dose, and results were significant as compared with control. Methanolic extract of T. glabra produced significant [P<0.05] analgesic effects at the dose of 500mg/kg in the acetic acid induced writhing test and the formalin test. In conclusion, results show that the crude methanolic extract of T. glabra possess sedative as well as potent analgesic effects. Present pharmacological studies are the first ever studies conducted on the methanolic extract of T. glabra

ABSTRACT

The purpose of this study was to evaluate the antibacterial, antifungal and antioxidant activities of medicinal plants. The antibacterial activity of methanolic extracts of three medicinal plants [Swertia chirata, Terminalia bellerica and Zanthoxylum armatum] were tested against Gentamicin [standard drug] on eleven gram positive and seventeen gram negative bacteria by agar well method. It was revealed that seven-gram negative and six gram positive bacterial species were inhibited by these plant extracts. Minimum inhibitory concentrations [MIC] of the extracts were determined by broth micro-dilution method. The significant MIC value of Swertia chirata was 20mg/ml against Serratia marcesens, Zanthoxylum armatum was 10 mg/ml against Aeromonas hydrophila and Terminali bellerica was 20mg/ml against Acinetobacter baumanii as well as Serratia marcesens. Antifungal screening was done for methanolic extracts of these plants by agar well method with the 6 saprophytic, 5 dermatophytic and 6 yeasts. In this case Griseofulvin was used as a standard. All saprophytes and dermatophytes were showed resistance by these plants extracts except Microsporum canis, which was inhibited by Z. armatum and S. chirata extracts. The significant MIC value of Zanthoxylum armatum was 10mg/ml against Microsporum canis and Swertia chirata was 10mg/ml against Candida tropicalis. The anti-oxidant study was performed by DPPH free radical scavenging assay using ascorbic acid as a reference standard. Significant antioxidant activities were observed by Swertia chirata and Zanthoxylum armatum at concentration 200microg/ml was 70% DPPH scavenging activity [EC[50]=937.5microg/ml] while Terminalia bellerica showed 55.6% DPPH scavenging activity [EC[50]=100ug/ml]. This study has shown that these plants could provide potent antibacterial compounds and may possible preventive agents in ROS related ailments

ABSTRACT

Most of the species of genus Salvia are famous for having medicinal properties due to their chemical constituents. Salvia bucharica [Lamiacea] is found in Balochistan near Quetta in Hannaurak and Kalat. It is used in traditional system of medicine and claims to cure liver ailments. In current study crude methanolic extract [CME] of Salvia bucharica was obtained from the leaves and tested for hepatoprotective activity and possible toxicity in rabbits. Liver toxicity was induced in rabbits by administration of carbon tetra chloride [CCl[4]] and evaluated by biochemical tests and histopathology of tissues. In this study rabbits were divided in to 3 groups [5 rabbit in each group]. Rabbits of group I [control] were administered only vehicle [0.9% sodium chloride] orally. Rabbits of group II were given CCl[4] and group III were treated with CCl[4] and S. bucharica CME orally. For hepatoprotective effect serum enzyme level and total protein level were calculated. Histopathology of liver sections of rabbits was also carried out to observe protective effect. Biochemical, hematological and histoptahological parameters were studied on rabbits for toxicological studies. S. bucharica CME showed significant liver protection with reduction in total bilirubin, direct bilirubin, Alanine aminotransferase [ALT], Aspartate aminotransferase [AST], Alkaline phosphatase [ALP], gamma glutamyl transpeptidase [gamma-GT]. And decrease in Albumin and globulin. In toxicological studies, biochemical and histoptahological parameters showed no significant toxicity in liver, heart and kidneys. It is concluded that S. bucharica CME showed hepatoprotective effects with nontoxic profile

ABSTRACT

Qualitative and quantitative analysis of plant extracts can be achieved by using different spectroscopic techniques. In current research work we deal with the nature of the absorption and spectra of extract of Acorus calamus, Artemisia absinthium and Bergenia himalaica using FTIR spectroscopic technique. The present study was focused on standardization of crude extracts by utilization of infrared light. The spectra of crude extracts [A. calamus, A. absinthium and B. himalaica] displayed very clear diagnostic peaks of functional groups i.e. O-H alcoholic/acid, C-H alkyl and aromatic ring, carbonyl, and C-O-C groups. The spectra of all the three plants did not show any peak at 2220-2260cm[-1], which is indicative of the absence of nitrogen containing groups. These results exhibited that these plants does not contain any toxic substances
