Zootherapy as traditional therapeutic strategy in the Cholistan desert of Bahawalpur-Pakistan.

The use of traditional medicines has tremendously increased over the past few decades. Approximately 80% of the world's population relies on traditional medicines for their primary healthcare needs because of their cost effectiveness and efficiency with no or minimal side effects. Zootherapy refers to the use of medicines that are prepared or derived from animals or from their products. The current study documented the folk knowledge related to the practice of various animal-derived products and ethnozoological based drugs used as medicines by the residents of the Cholistan desert of Bahawalpur (Pakistan). In this regard 46 knowledgeable and reliable elderly people, hakims and spiritual healers ranging from 35-60 years of age having knowledge related to zootherapy were included in the current study. A field survey from February 2006 to November 2007 was conducted by interviewing the selected respondents through a structured questionnaire. They provided knowledge regarding the use of animals and their derived products in traditional medicine. The zootherapeutic knowledge was based on both domestic animals as well as wild animals. A total of 20 animal species were included in the study, among which nine animals were domestic while 11 were wild animals. Among selected animals, nine were mammals, four birds, four reptiles and three insects. It was reported that camel was the most commonly used (n = 32 respondents) among mammals while Pigeon (n = 39 respondents), Spiny-tailed lizard (n = 41 respondents) and Indian honey bee (n = 27 respondents) among birds, reptiles and insects, respectively, have significant use for the treatment of different diseases. Based on this communication we could recommend that this type of abandoned knowledge should be considered for the management and conservation of faunistic resources. However, the advantageous role of animals and their products was reported but more extensive research is required to explore the bioactive constituents in the raw material of these animals responsible for their beneficial effects.

In vitro comparative evaluation of Tamarix gallica extracts for antioxidant and antidiabetic activity.

Tamarix gallica known as Jhau is traditionally used as expectorant, liver tonic, laxative, astringent, and antidiarrheal. The current study was proposed to determine the in vitro antioxidant, antidiabetic properties of the methanolic, ethanolic, and aqueous extracts of Tamarix gallica arial part, subsequently the phytochemical evaluation. Hence, Tamarix gallica arial part extracts were extracted with methanol (MthTg), ethanol (EthTg), and distilled water (AqTg). Extracts phytochemical analysis were accomplished to identify the phenolic components (TPC and TFC). Extracts antioxidant property was evaluated by DPPH, FRAP, and ABTS assay. For antidiabetic property, α-amylase and α-glucosidase inhibitory activities were assessed. One Way ANOVA was applied statistically by means of software SPSS Statistics 23 and attained data were definite as mean ± standard deviation. Result revealed that EthTg have the maximum TPC and TFC levels than MthTg and AqTg. Antioxidant property in relations of DPPH (lowest IC50 = 1.309 ± 0.31), FRAP (323.51 ± 2.32), and ABTS (266.97 ± 25.14) assay was also highest in EthTg. EthTg was also exposed highest α-amylase and α-glucosidase inhibition activity with lower IC50 (1.116 ± 0.051; 0.402 ± 0.2, respectively). The extracts antioxidant and antidiabetic activities order was as EthTg > MthTg > AqTg. TFC and TPC also revealed directly proportional correlation with antioxidant, and antidiabetic properties of the Tamarix gallica arial part extracts. Results noticeably stated that the ethanolic extract of Tamarix gallica have the highest antioxidant and antidiabetic properties. Tamarix gallica has competency to reduce the oxidative stress and can be utilized in the management of diabetes.

Prevalence of transfusion-transmitted infections in multiple blood transfusion-dependent thalassemic patients in Asia: A systemic review.

BACKGROUND: Thalassemia is a hereditary hemolytic anemia marked by a defect in synthesizing one or more globin chains in hemoglobin. In Pakistan, approximately 10,000 patients with thalassemia are primarily dependent on blood transfusions. The ß-thalassemia patients require blood transfusions and iron chelation therapy. Patients who need blood transfusions are at an increased risk of contracting transfusion-transmitted infections (TTIs) such as hepatitis B and C viruses (HBV and HCV, respectively), as well as the human immunodeficiency virus (HIV). OBJECTIVE: This systemic review aims to assess the prevalence of TTIs in transfusion-dependent ß-thalassemia patients in Asia. METHODS: The data for the systematic review were gathered from PubMed, Google Scholar, the Directory of Open Access Journals (DOAJ), and ScienceDirect using the following keywords: "prevalence, HBV, HCV, HIV, thalassemia, and transfusion-transmitted infections (TTIs)," and so on. This review includes the research articles that address the prevalence of viral infections in thalassemic patients following blood transfusion. RESULTS: A preliminary search of various databases identified 231 potential studies. 157 duplicate studies were eliminated, and the eligibility of 59 full-length articles was determined. Only 43 studies met the inclusion criteria. Among the 43 studies analyzed, 11 reported a high prevalence of HCV alone in thalassemic patients, while 21 reported a high prevalence of HCV and HBV infection in thalassemic patients. Eight studies reported the prevalence of all three TTIs examined, namely, HCV, HBV, and HIV, in patients with transfusion-dependent thalassemia. CONCLUSION: Preventable transfusion-transmitted infections occur frequently, and robust national policies and hemovigilance are required to detect and mitigate the infection risk.

Withania somnifera Chemical Constituents' In Vitro Antioxidant Potential and Their Response on Spermatozoa Parameters.

Background: Phytomedicine is becoming more acceptable as an alternative medicinal approach in the modern era. Objectives: The current study examined the antioxidant capacity and in vitro response of phytochemical constituents of Withania somnifera (Ashwagandha) on standard parameters of healthy volunteer semen. Methods: The phytochemicals and their pharmacological response in a hydroethanolic (30:70 v/v) extract of W. somnifera roots were determined using standard protocols. Results: The constituents included flavonoids, phenolic acids, alkaloids, and terpenoids were reported. High-performance liquid chromatography and Fourier-transform infrared spectroscopy determined a diverse array of biologically active chemical constituents in the extract. The extract of W. somnifera exhibits substantial antioxidant properties, including total antioxidant capacity, 2,2-diphenyl-1-picrylhydrazyl inhibition, H2O2 scavenging, and Fe3+ reducing potential (P < .05). The analysis of essential natural minerals explored adequate levels determined using atomic absorption spectrophotometer. Cytotoxic studies revealed significant thrombolytic, RBC membrane stabilization, and DNA damage protection activity (P < .05) while remaining non-mutagenic against Salmonella typhi TA98 and TA100. The best protective response of W. somnifera extract on human semen parameters (n = 30), such as total motility, progressive motility, and viability, demonstrated a significant (P < .05) improvement, particularly at the dose of 25 µg/mL and 50 µg/mL. Conclusion: The study concludes that W. somnifera possesses favorable in vitro characteristics that could aid in the preservation of sperm during intrauterine insemination and in vitro fertilization.

Hantavirus diseases pathophysiology, their diagnostic strategies and therapeutic approaches: A review.

Hantaviruses are enveloped negative (-) single-stranded RNA viruses belongs to Hantaviridae family, hosted by small rodents and entering into the human body through inhalation, causing haemorrhagic fever with renal syndrome (HFRS) and hantavirus pulmonary syndrome (HPS) also known as hantavirus cardiopulmonary syndrome (HCPS). Hantaviruses infect approximately more than 200 000 people annually all around the world and its mortality rate is about 35%-40%. Hantaviruses play significant role in affecting the target cells as these inhibit the apoptotic factor in these cells. These viruses impair the integrity of endothelial barrier due to an excessive innate immune response that is proposed to be central in the pathogenesis and is a hallmark of hantavirus disease. A wide range of different diagnostic tools including polymerase chain reaction (PCR), focus reduction neutralization test (FRNT), enzyme-linked immunosorbent assay (ELISA), immunoblot assay (IBA), immunofluorescence assay (IFA), and other molecular techniques are used as detection tools for hantavirus in the human body. Now the availability of therapeutic modalities is the major challenge to control this deadly virus because still no FDA approved drug or vaccine is available. Antiviral agents, DNA-based vaccines, polyclonal and monoclonal antibodies neutralized the viruses so these techniques are considered as the hope for the treatment of hantavirus disease. This review has been compiled to provide a comprehensive overview of hantaviruses disease, its pathophysiology, diagnostic tools and the treatment approaches to control the hantavirus infection.

Progress and prospects in the management of bacterial infections and developments in Phytotherapeutic modalities.

The advent of antibiotics revolutionized medical care resulting in significantly reduced mortality and morbidity caused by infectious diseases. However, excessive use of antibiotics has led to the development of antibiotic resistance and indeed, the incidence of multidrug-resistant pathogens is considered as a major disadvantage in medication strategy, which has led the scholar's attention towards innovative antibiotic sources in recent years. Medicinal plants contain a variety of secondary metabolites with a wide range of therapeutic potential against the resistant microbes. Therefore, the aim of this review is to explore the antibacterial potential of traditional herbal medicine against bacterial infections. More than 200 published research articles reporting the therapeutic potential of medicinal plants against drug-resistant microbial infections were searched using different databases such as Google Scholar, Science Direct, PubMed and the Directory of Open Access Journals (DOAJ), etc., with various keywords like medicinal plants having antibacterial activities, antimicrobial potentials, phytotherapy of bacterial infection, etc. Articles were selected related to the efficacious herbs easily available to local populations addressing common pathogens. Various plants such as Artocarpus communis, Rheum emodi, Gentiana lutea L., Cassia fistula L., Rosemarinus officinalis, Argemone maxicana L, Hydrastis canadensis, Citrus aurantifolia, Cymbopogon citrates, Carica papaya, Euphorbia hirta, etc, were found to have significant antibacterial activities. Although herbal preparations have promising potential in the treatment of multidrug-resistant bacterial infection, still more research is required to isolate phytoconstituents, their mechanism of action as well as to find their impacts on the human body.

Determination of oil contents from eight varieties of olea europaea (Olive) grown in Pakistan.

The olive (Olea europaea L.) is a worldwide famous tree crop having valuable commercial role due to nutritional as well as therapeutic benefits obtained from its edible oil. Eight varieties of Olea europaea L. fruits were obtained from three Agricultural research institutes located in different areas of Pakistan including Quetta, Lorallia and Zhob to extract and determine their oil contents by conventional method as solvent extraction (soxhlet apparatus). Statistical analysis showed significant (p = 0.002) difference in oil composition of collected plants. Highest amount (percentage) of oil was obtained from Gemlik variety (65%) from Lorallia and lowest oil content from Dolece-agogia variety (17.5%) collected from Quetta. Further research is under consideration to rule out best suitable factors including some soil and environmental factors to obtained more potential cultivars of Olea europaea in Pakistan.

Naegleria fowleri: Sources of infection, pathophysiology, diagnosis, and management; a review.

Naegleria fowleri, a thermophilic flagellate amoeba known as a "brain-eating" amoeba, is the aetiological agent of a perilous and devastating waterborne disease known as primary amoebic meningoencephalitis (PAM), both in humans as well as in animals. PAM is a rare but fatal disease affecting young adults all around the world, particularly in the developed world but recently reported from developing countries, with 95%-99% mortality rate. Swimmers and divers are at high risk of PAM as the warm water is the most propitious environment adapted by N. fowleri to cause this infection. Infective amoeba in the trophozoite phase enter the victim's body through the nose, crossing the cribriform plate to reach the human brain and cause severe destruction of the central nervous system (CNS). The brain damage leads to brain haemorrhage and death occurs within 3-7 days in undiagnosed cases and maltreated cases. Though the exact pathogenesis of N. fowleri is still not known, it has exhibited two primary mechanisms, contact-independent (brain damage through different proteins) and contact-dependent (brain damage through surface structures food cups), that predominantly contribute to the pathogen invading the host CNS. For the management of this life-threatening infection different treatment regimens have been applied but still the survival rate is only 5% which is ascribed to its misdiagnosis, as the PAM symptoms closely resembled bacterial meningitis. The main objectives of this review article are to compile data to explore the sources and routes of N. fowleri infection, its association in causing PAM along with its pathophysiology; latest techniques used for accurate diagnosis, management options along with challenges for Pakistan to control this drastic disorder.

Assessment of Cucumber Genotypes for Salt Tolerance Based on Germination and Physiological Indices.

Soil salinity is one of the primary problem for agricultural crops which causes a great loss in crop production in Pakistan and worldwide. Various approaches have been implemented to overcome salinity problem. Assembly of crops for the enhancement of salt tolerance is a good strategy to achieve cost-effective yields. Cucumber is considered as one of the leading vegetable crop around the world for the nourishment of human being as source of nutrients, minerals, and vitamins. Screening of 12 cucumber genotypes using some physiological indices, that is, seedling germination stress tolerance index, plant height stress tolerance index, root length stress tolerance index, shoot and root dry weight stress tolerance index, and shoot and root fresh weight stress tolerance index were performed for the identification of salt tolerance. Using the above characteristics genotypes, Valley and HC-999 were categorized as tolerant, Safaa and Debra as medium tolerant, while Thamin-II identified as medium sensitive and NSC-CM1 and Akbar are classified as sensitive genotypes of cucumber. According to the current study findings, the screened cucumber genotypes for salinity tolerance can also be suggested to farmers for the improved production and yield of crop at saline soil.

Therapeutic potential of medicinal plants for the management of urinary tract infection: A systematic review.

Urinary tract infection (UTI) is one of the most severe public health problem affecting both sexes but females are more susceptible due to the differences in urogenital and reproductive anatomy, physiology and lifestyle. As in UTI, different parts of the urinary tract are affected and morbidity due to UTI is more common in women of all ages and older men. Due to multi-drug resistant strains and high recurrence rate, UTI has become a major socioeconomic burden. The current review article was aimed to describe the natural therapeutic strategies to manage and cure the UTI. For this purpose, different databases including Google Scholar, Cochrane database, and PubMed etc. were explored. Inclusion criteria were any research article investigating the current therapy of UTI. It was found that microbial infections including Escherichia coli, Enterococcus faecalis and Klebsiella species are the major causes of UTI with different signs and symptoms including painful urination or dysuria, hematuria, urinary urgency, burning micturition, frequent urination, nausea, and vomiting. Antibiotics like trimethoprim, sulfamethoxazole, quinolone etc. as the first choice of the drug are used worldwide. However, due to microbial resistance, several life-threatening side effects, repeated high doses, high cost and low efficacy of these antibiotics motivated the researchers to explore natural remedies for the treatment of UTI. Herbal medicines are effective to combat bacterial resistance with high efficacy, and easy availability with minimal or no side effects. For these reasons it has attained the attention of researchers wanting to explore the herbal treatment of UTI. Vaccinium macrocarpon, Tribulus terrestris, Trachyspermum copticum, Cinnamomum verum and Hybanthusenn easpermus are some common medicinal plants reported to have therapeutic potential for the management and cure of the UTI. Although herbal medicines have more potential over conventional medicine but more discoveries are required to explore the phytoconstituents and their mechanism of action responsible for the management and cure of UTI.

Hexose monophosphate shunt, the role of its metabolites and associated disorders: A review.

The hexose monophosphate (HMP) shunt acts as an essential component of cellular metabolism in maintaining carbon homeostasis. The HMP shunt comprises two phases viz. oxidative and nonoxidative, which provide different intermediates for the synthesis of biomolecules like nucleotides, DNA, RNA, amino acids, and so forth; reducing molecules for anabolism and detoxifying the reactive oxygen species during oxidative stress. The HMP shunt is significantly important in the liver, adipose tissue, erythrocytes, adrenal glands, lactating mammary glands and testes. We have researched the articles related to the HMP pathway, its metabolites and disorders related to its metabolic abnormalities. The literature for this paper was taken typically from a personal database, the Cochrane database of systemic reviews, PubMed publications, biochemistry textbooks, and electronic journals uptil date on the hexose monophosphate shunt. The HMP shunt is a tightly controlled metabolic pathway, which is also interconnected with other metabolic pathways in the body like glycolysis, gluconeogenesis, and glucuronic acid depending upon the metabolic needs of the body and depending upon the biochemical demand. The HMP shunt plays a significant role in NADPH2 formation and in pentose sugars that are biosynthetic precursors of nucleic acids and amino acids. Cells can be protected from highly reactive oxygen species by NADPH 2 . Deficiency in the hexose monophosphate pathway is linked to numerous disorders. Furthermore, it was also reported that this metabolic pathway could act as a therapeutic target to treat different types of cancers, so treatments at the molecular level could be planned by limiting the synthesis of biomolecules required for proliferating cells provided by the HMP shunt, hence, more experiments still could be carried out to find additional discoveries.

Frequency of different types of gastric varices in patients with cirrhosis due to chronic hepatitis C.

OBJECTIVE: To determine the frequency of different types of gastric varices in patients with hepatitis C virus-related cirrhosis. METHODS: The observational cross-sectional study was conducted from August 2014 to August 2015 at Aziz Bhatti Shaheed Teaching Hospital, Gujrat, Pakistan, using non-probability consecutive sampling. Patients having liver cirrhosis only due to chronic hepatitis C virus, portal vein diameter >12mm or spleen size >12cm in long axis and ascites with no previous history of variceal banding were included. Patients having cirrhosis due to other causes were excluded. Data was collected using a proforma that was filled by taking history, laboratory studies, abdominal ultrasound and upper gastrointestinal endoscopy. Gastric varices were classified using Sarin classification. SPSS 20 was used for statistical analysis. RESULTS: Out of 205 patients undergoing esophago-gastroduodenoscopy, 122(59.5%) were male and 83(40.5%) were female with an overall mean age of 49.5±7.49 years. Gastric varices were present in 30(14.6%) patients. Among them, type 1 was present in 23(76.71%), type 2 in 6(19.86%) and isolated gastric varices type 1 in 3(10.27%).Isolated gastric varices type 2 was not present in any patient. CONCLUSIONS: Gastric varices were present in minority of patients undergoing esophago-gastroduodenoscopy, and among them, gastroesophageal varices type 1 was the most common, while isolated gastric varices type 2 was not present in any patient.

Efficacy of differently applied tyrosine and tryptophan for modulation of phenolic metabolism in Trachyspermum ammi (L.) sprague seedlings.

Phenolics are pharmaceutically important molecules. Tyrosine and tryptophan are precursors of phenolic metabolism. It was aimed to investigate the potential of exogenously introduced precursors on the phenolic contents in Trachyspermum ammi (L.) Sprague seedlings. The seeds of two local varieties (Chakwal and Desi) were grown in completely randomized design in a growth chamber at 19 ± 2°C with two amino acids (tyrosine and tryptophan) applied (priming and supplementation in rooting medium) at two treatment levels (0, and 1%). Ten days old seedlings were harvested and subjected for growth (root and shoot length, fresh weight and dry weight) and phenolic estimation was done by HPLC method. Presence of seven phenolic acids including quercitin, chromatotropic acid, gallic acid, chlorogenic acid, sinnapic acid, trans 4 hydroxy 3 methoxy cinamic acid and P-courmeric acid was confirmed in both varieties with dissimilar fraction. Poor growth was observed by "Desi" under controlled conditions that were efficiently enhanced by tyrosine and tryptophan treatments. As precursors both amino acids differed for allosteric regulation of the pathway. That varied from application to application and variety to variety too for a pattern of phenolic accumulation. In conclusion, tyrosine and tryptophan application can be useful for farmers for improved growth of T. ammi and for pharmaceutical scientists to modulate metabolites of interest.
