Continuing pharmacy education and training in libya

Lifelong learning is becoming part of the philosophy of professional education. Continuing medical education is the responsibility of all personnel who are responsible for the delivery of components of the health care delivery system. Continuing education is becoming increasingly obvious for medical universities, hospitals, and health care providers. Pharmacists who practice in a community pharmacy and hospital, and who are participating in residency recognize that the traditional role of the pharmacist is changing. Over the last decades, a host of new services have been identified as a function of the pharmacist [1]. A review of these services revealed a personal commitment to continuing education. It is the absolute need to develop a level of competence that will improve patient care. In Libya, pharmacists working in the community practice setting are pharmacists with a diploma of pharmacy or with a Bachelor of Pharmaceutical Science, Master of Science, and Doctor of Pharmacy (Pharm D). The main objective is that the graduates possess the knowledge and skills needed to perform optimally to man the pharmaceutical services [1, 2]. Patient's expectations from pharmacists are that the medicine should be effective, safe and affordable. Other expectations from Libyan pharmacists would be to dispense the drugs according to the rules with the right advice on how and when the medicines should be used, and what to do in the case of adverse drug reactions, and the provision of advice on common illnesses. Nevertheless, it is an undeniable fact that the pharmacist has failed to provide all these patient-oriented services [3]. It should be noted that the quality of pharmacy education and training can be improved through certain processes of accreditation.

Aqueous extract of hybanthus enneaspermus exhibited aphrodisiac potentials in fluoxetine-induced sexually-impaired female rats

Hybanthus enneaspermus, traditionally used as an aphrodisiac was investigated for its potential to reverse antidepressant-induced sexual dysfunction in female rats. The aqueous extract was evaluated for secondary metabolite, amino acid and mineral constituents. Alkaloids, tannins, flavonoids, anthraquinones, steroids, terpenoids, phenolics, calcium, potassium, sodium, glutamine and leucine are some of its notable constituents. 60 healthy, sexually responsive female albino rats (144.7±5.9 gm) were divided into six groups (A-F) of 10 rats each; of which 50 were induced into sexual dysfunction. Rats in group A were administered distilled water throughout the experimental period and served as a control group, while rats induced into sexual dysfunction (Groups B-F) by fluoxetine were given water, the reference medication (Tadalafil) and oral doses of the extract (250, 500, and 1000 mg/kg body weight) once daily for seven days, respectively. When administered to sexually active rats, fluoxetine significantly decreased the frequency of darting, hopping, lordosis, genital grooming, and licking behavior by 57.4%, 42.5%, 43.9%, 64.0%, and 41.8%, respectively. However, the latency of darting, hopping and lordosis were significantly increased by 50.6%, 47.7%, and 54.9%, respectively. Hybanthus enneaspermus aqueous extract administered at doses of 250, 500, and 1000 mg/kg significantly reversed fluoxetine-mediated changes in all sexual behavior parameters. The extract's ability to reverse the characteristics of sexual behavior at 1000 mg/kg was comparable to those of tadalafil-treated rats. Additionally, all the extract dosages reversed the levels of blood luteinizing hormone, follicle-stimulating hormone, progesterone, prolactin and estrogen after it has significantly been altered by fluoxetine. The results indicated that the aqueous extract of Hybanthus enneaspermus improved the proceptive, receptive and orientational behavior of rats. The extract also enhanced reproductive hormone concentration by restoring sexual competence in sexually-impaired female rats. The findings of this study provide further evidence in favor of Hybanthus enneaspermus widespread usage in the management of female sexual dysfunction.

Body image and identity: a look into select short stories of bhabendra nath saikia"

The human body has been theorized in many ways, including the entire notion of the woman as a human creation. It is generally agreed that this concept refers to our perceptions, thoughts, and feelings about our bodies, which influence our behaviour about our bodies. The article examines numerous authors whose individual genealogies meet on the common ground of identity theory and women's lives and is supported by a theoretical framework based on conceptions of identity, body-image and self-image in women and feminist discourse. This paper probes into the concepts of identity in women through the literary canvas of Dr. Bhabendra Nath Saikia and demonstrates the effects of body image and self-image on the development of identity. Of course, an extensive discussion of the short stories of Dr. Saikia is beyond the scope of this paper. The aim of this paper is to analyse the concepts through the two short stories short titled "Dhura Xaap" (ঢ োৰো সোপ 1958) and "Sringkhol" (শ ৃংখল, 1970) by Dr, Bhabendra Nath Saikia. The paper seeks to explore the concepts of self-image, identity and body image through three female characters ‘Chandrika’, ‘Janeki’ and ‘Ambika’.

Pharmacognostic and preliminary phytochemical investigation of aerial parts of centella asiatica linn

In the Indo-Pak subcontinent, the traditional systems of medicine, both Ayurvedic and Unani, are primarily based on herbs and herb-based preparation for therapy. Therefore, the importance of the herbal identification process remains critical in achieving the desired and successful therapeutic effect. To support the manufacturers and practitioners of both systems, many herbs are still collected from wild sources, as herbal farming is not very developed in this part of the world. During a survey program conducted in different areas of Pakistan, significant lacks and gaps were noted to be present in the identification & characterization of herbs, which needs to be addressed and fulfilled as many species look alike apparently or physically but have different biological or pharmacological activity. Based on this objective and approach, Centella asiatica was selected for the pharmacognostic and preliminary phytochemical investigation to establish a better correlation and to provide useful methods in its identification as the use of Centella asiatica is very common in Pakistan and other South Asian countries for CNS disorders therapy. Therefore, this study aimed to develop & report some and rapid identification methods for Centella asiatica. The present study includes physical, physicochemical, preliminary phytochemical and fluorescence analysis. For the first time, in the present study, NIR and FT-IR spectra of Centella asiatica have been reported for identification. The findings of the present study are quite promising and can be helpful for the manufacturers and researchers in the identification and development of Centella asiatica-based new drugs or formulations.

Anti-emetic activity of cleome brachycarpa vahl ., and cleome viscosa l., (leaves) in chicks

Cleome brachycarpa Vahl . and Cleome viscosa L. were evaluated for anti-emetic activity in the copper sulfate-induced chick emesis model. Emesis was induced by copper sulfate (50 mg/kg), and the methanolic extracts of leaves were tested orally at a dose of 150 mg/kg. Chlorpromazine (150mg/kg orally) was used as standard anti-emetic drug. The anti-emetic activity was determined by calculating the mean decrease in the number of retching as compared with the control. Cleome brachycarpa and Cleome viscosa showed comparable anti-emetic activity with chlorpromazine.Cleome brachycarpa Vahl ., and Cleome viscosa L., leaves extract in a dose of 150 mg/kg body weight., reduced the numbers of retches by 57.57% and 43.06%. Cleome brachycarpa significantly (**P<0.005) reduced the number of retches. The group of chicks treated with chlorpromazine had 45 retches compared to the 71 retches of the control group, thus chlorpromazine reduced the retches by 36.99%. From the results, it is clear that Cleome brachycarpa Vahl. and Cleome viscosa L. leaves extracts have antiemetic potential and are comparable with standard chlorpromazine. Although the result is significant the mode of action is not known. Antiemetic activity by using copper sulfate proposed 5-HT3, 5-HT4, or NK1 receptor antagonism. Therefore, the extracts effectively prevented its effect and had a peripheral anti-emetic action. As mentioned earlier, triterpenoids such as brachycarpone, deacetoxybrachycarpone, cabralealactone and ursolic acid are reported from Cleome brachycarpa6, whereas flavonoids are reported from Cleome viscosa. Flavonoids and triterpenoids possess anti-emetic properties18. So, if flavonoids and triterpenoids are present in the studied extracts, the observed anti-emetic effects may be due to flavonoids and triterpenoids. The present study is on the preliminary level, and further investigation is required to confirm the anti-emetic effect of Cleome brachycarpa Vahl ., and Cleome viscosa L. leaves and determine the compounds responsible for this activity with their possible mode of action.

Anti-emetic effects of bioactive natural products

Emesis, also known as nausea and vomiting, are common symptoms associated with ingestion of toxicants, drug side effects, advanced terminal diseases such as cancer and postoperative procedures. Emesis is mediated through the coordinated action of central and peripheral regulatory centres that involve receptors including dopamine Type 2, serotonin, muscarinic cholinergic, histamine, cannabinoids and NK-1 receptors. Many anti-emetic drugs targeting these receptors are currently in use, but they also cause undesirable side effects such as excessive sedation, hypotension, dry mouth, dysphoria, hallucinations and extrapyramidal signs. This review highlights the pharmacological mechanism of emesis, current antiemetic drugs, and a detailed analysis of in vitro and in vivo anti-emetic bioassay models. The pharmacology of crude natural products extracts and purified anti-emetic compounds (cannabinoids, chalcones, diarylheptanoids, flavonoids, hydroxycinnamic acids, lignans, phenylpropanoids, polysaccharides, saponins, terpenes and glycosidic derivatives) are also systematically presented with their mechanism of action. The potential of natural products as sources of new clinically proven anti-emetic drugs is discussed.

Analgesic activity of leaves, flowers and fruit peel of luffa cylindrica (l.) roem.

Ethanol extracts of leaves, male flowers and fruit peel of Luffa cylindrica (L.) Roem., were evaluated for analgesic effect using the analgesy meter test, a mechanically induced pain model. Extracts at 500 mg/kg, p.o., were tested and compared with diclofenac sodium 50mg/kg as a standard analgesic drug. The mechanical force was applied to the rat's paw and continuously increased. The point at which the rat can’t bear further pressure and starts to struggle to free the paw was taken as a nociceptive response. Readings were taken before and after 1, 2 and 3hr following drug administration. The analgesic response was continuously increasing till 3hrs. Tested extracts produced significant and comparable analgesic effects as with diclofenac sodium.

Natural antiemetics: an overview

Emesis encompasses the forceful expulsion of the stomach's contents via the mouth or sometimes the nose. The adverse effects of currently available anti-emetic agents potentiate the natural product researchers to explore natural anti-emetics with fewer side effects. The presented communication reviews the anti-emetic effect of two hundred and forty-five plants belonging to seventy-eight families in different parts of the world. It also outlined the anti-emetic effect of plant extracts and isolated secondary metabolites studied through a variety of animal models of emesis. The reported anti-emetic plants in different countries and cultures and the scientific studies on extracts may help in the identification of promising single chemical compound(s) that may be used as potential leads for developing safe anti-emetic agents in future. Moreover, the reported secondary metabolites having the same effect may open the door for the search for the same secondary metabolites from other natural sources. This review will provide useful information for discovering natural anti-emetic compounds and fill the gaps in knowledge.

Antiemetic activity of bergenin from peltophorum roxburghii l.

The presented study initially attempted to discover bergenin as an antiemetic compound isolated from Peltophorum roxburghii L. leaves. It is the extension of antiemetic activity from the methanol extract of Peltophorum roxburghii L. leaves. The antiemetic activity was assessed using copper sulfate-induced emesis in the chick’s model. Bergenin (25 mg/kg, p.o.) exhibited significant antiemetic activity compared to the standard drug, chlorpromazine. This is the first time that bergenin has declared antiemetic activity. Bergenin has already been evaluated positively for its anti-inflammatory activity, and this paper will report its antiemetic activity. Both the activities of the same compound may be beneficial for drug design against the disease, as they have anti-inflammatory and antiemetic symptoms like migraines. The preliminary antiemetic evaluation of bergenin was conducted on a single dose due to the low yield of Bergenin. However, the result was significant in terms of the standard used. Further, the isolation and purification of Bergenin are in the process of establishing detailed data on different doses of Bergenin.
