Like the western and conventional medicines, Traditional Chinese medicine (TCM) has promising results in the ailment of diabetes and its associated complications. But still the use of TCM is refrained for further explorations due to inadequate knowledge of active pharmaceutical ingredient and its isolation. Thus, this review will highlight some of the key concepts and rational behind the therapeutic regimen of TCM aiming towards diabetes treatment. A detailed study of all the articles including research as well as reviews, which were available on the world wide web was performed. The review includes MEDLINE and EMBASE databases using keywords alone or in combinations, such as diabetes, diabetic complications, Chinese therapy, traditional chinese medicine, diabetic neuropathy, diabetic nephropathy, diabetic retinopathy, diabetic complications, α-amylase and several others. TCM collectively is an effective and comparatively safe in the treatment of diabetes mellitus and its associated complications. Significant results are seen in monotherapy and in combination therapy with current conventional drugs. The effects include controlling glycemic levels along with the mitigation of diabetes associated complications. Focus on clinical trials and further investigations might help in concluding TCM as one of the most effective and safe treatment therapies. TCM holds enormous potential by virtue of its mechanism of action by maintaining the homeostasis in the body and thereby exhibiting pharmacological action.</p> 2020-03-12T00:00:00+00:00 ##submission.copyrightStatement## http://jpionline.org/index.php/ijpi/article/view/437 3D Printing in Pharmaceutical Technology – A Review 2020-03-13T11:49:49+00:00 Ravikumar Tamil Ponni tamilvijay181@gmail.com Mahalingam Swamivelmanickam tamilvijay181@gmail.com Sivagnanam Sivakrishnan sivacdm82@gmail.com <p style="text-align: justify;">Three-dimensional printing is a revolutionary technique that uses computer aided design software and programming to create three dimensional objects by placing material on a substrate. 3D printing is an additive layer manufacturing techniques, where consecutive layers of material are deposited or solidified to form a 3D structure.

In the current study, the ChA was challenged against intracerebroventricular (ICV)-streptozotocin (STZ)-induced neurotoxicity to determine its therapeutic potential in dementia. STZ was infused bilaterally (3 mg/kg/icv) on day 1<sup>st</sup> and 3<sup>rd</sup> after surgery. ChA (25, 50 and 100 mg/kg/p.o) was administered from 7<sup>th</sup> day onwards up to 21<sup>st</sup> day following 1<sup>st</sup> ICV-STZ infusion. Spatial and non-spatial memory was evaluated and terminally the animals were sacrificed and hipoocampal brain regions were used to identify biochemical and histopathologicsal alterations. Ventricular administration of STZ in rats caused impairment in learning and memory indicating cognitive dysfunctions. The observed cognitive dysfunctions was also associated with significant alterations in hippocampal biochemistry, including elevation in oxidative stress, found to significantly shorten the latency time on the MWM and ORT which was associated with increase in oxidative stress (lipid peroxidation and nitrite), compromised antioxidant defense (reduced glutathione), neurotransmitter alteration (AChE, dopamine, noradrenaline, 5-hydoxytryptamine, Gama amino butyric acid and glutamate) and elevation in neuroinflammatory cytokine (IL-1 β, IL-6 and TNF- α) levels. The number of apoptotic neurons was increased in hippocampus tissue after ICV-STZ administration. The histopathological studies in the brain of rats also supported that ChA markedly reduced the ICV-STZ-induced histopathological changes and well preserved the normal histological architecture of the hippocampus. The study demonstrates the effectiveness of ChA, as a powerful antioxidant, anti-inflammatory and neuromodulatory in preventing the all these detrimental effects induced by STZ. ChA treatment significantly prevented the ICV-STZ-induced memory deficit by attenuating the hippocampal neuronal loss, neuroinflammation and compromised antioxidant defense and cholinergic deficit in rats. Thus, ChA may have a therapeutic value for the treatment of AD.</p> 2020-03-12T00:00:00+00:00 ##submission.copyrightStatement## http://jpionline.org/index.php/ijpi/article/view/453 Ameliorative Effect of Salvadora persica (Miswak) on Cigarette Smoke Induced Anxiety and Depression in Rats 2020-03-13T11:49:50+00:00 Syed Imam Rabbani syedrabbani09@yahoo.com <p><strong>Objectives:</strong> The aim of the study is to evaluate the anxiolytic and antidepressant&nbsp;activity of<em> Salvadora persica</em> in cigarette smoke-induced neurobehavior&nbsp;changes in rats. <strong>Methods:</strong> The lyophilized decoction of <em>Salvadora</em><br><em>persica</em> (<em>S. persica</em>) was administered daily for four weeks by oral route at&nbsp;the doses 50, 100 and 200 mg/kg to the cigarette smoke exposed rats. The&nbsp;depression and anxiety studies were done by forced swim test and elevated&nbsp;plus maze test, respectively. The serum levels of monoamine oxidase-A&nbsp;and relative brain weight were also determined. The results were analyzed&nbsp;statistically by one-way ANOVA followed by Duncans’ multiple range tests.&nbsp;<em>p</em>&lt;0.05 was considered to indicate the significance of results. <strong>Results:</strong> The&nbsp;observation from the study indicated that exposure of cigarette smoke for&nbsp;eight weeks significantly (<em>p</em>&lt;0.01) enhanced the experimental parameters&nbsp;of depression and anxiety, besides increasing the monoamine oxidase-A&nbsp;and relative brain weight when compared with control animals. Administration&nbsp;of <em>S. persica</em> exhibited a dose-dependent inhibition in the neurobehavioral&nbsp;parameters. <em>S. persica</em> at 200 mg/kg produced significant (<em>p</em>&lt;0.01)&nbsp;antidepressant and antianxiety effects. The treatment was also found to&nbsp;reduce the serum monoamine oxidase-A and relative brain weight in the&nbsp;cigarette smoked animals.<strong> Conclusion:</strong> The data suggests that decoction&nbsp;of <em>S. persica</em> might possess antidepressant and anxiolytic properties in the&nbsp;cigarette smoke exposed animals.

The third and&nbsp;fourth group of animals received amifostine and DRDE-07 (210 and 250&nbsp;mg/kg&nbsp; respectively) through the oral route, 30 min before SM exposure.&nbsp;The clinical symptoms and body weight changes were observed daily and&nbsp;sacrificed on 7<sup>th</sup> day. Bronchoalveolar lavage fluid (BALF) and lung tissue<br>were collected for biochemical and histopathological studies. The following&nbsp;biochemical endpoints were studied in BALF (total cell count, lactate&nbsp;dehydrogenase, protein content, β-glucuronidase activity, MMP-2, 9 activity<br>and FSH) whereas reactive oxygen species (ROS), reduced glutathione&nbsp;(GSH), lipid peroxidation, superoxide dismutase, catalase and myeloperoxidase&nbsp;activity was measured in lung tissue. The above biochemical observations&nbsp;are also supported by histopathology studies. <strong>Results:</strong> Dermal&nbsp;exposure to SM significantly reduced body weight. The significant increase&nbsp;in BALF LDH leakage, protein content, cell number and MMPs activity in&nbsp;the SM exposed animals suggest disruption of endothelial barrier in the&nbsp;lung (<em>p</em>&lt;0.05). Significant ROS generation (<em>p</em>&lt;0.05) was observed in lung&nbsp;tissue of SM group which results in a significant decrease in SOD GSH<br>and CAT and an increase in MDA (<em>p</em>&lt;0.05). These alterations in BALF as&nbsp;well in lung tissue due to SM exposure was significantly prevented by the&nbsp;pretreatment of amifostine and DRDE-07 (<em>p</em>&lt;0.05). The histopathological&nbsp;observations also support the above results. The above results indicate that&nbsp;the preventive efficacy of DRDE-07 is better than amifostine. <strong>Conclusion:&nbsp;</strong>The percutaneous SM exposure-induced pulmonary damages were significantly&nbsp;protected by DRDE-07 than amifostine in mice.</p> 2020-03-12T00:00:00+00:00 ##submission.copyrightStatement## http://jpionline.org/index.php/ijpi/article/view/459 Development of Sheep Butter Based Cream for Dermal Wound Healing 2020-03-16T10:32:15+00:00 Rai Pratikcha pratikcharai212@gmail.com Das Sujit sujitdashpi@gmail.com Ghosh Tanmoy tanmoy.ps.ph@msruas.ac.in Deveswaran Rajamanickam tanmoy.ps.ph@msruas.ac.in Mohanta Tanmay tanmaymohanta9203@gmail.com Roy Kalyan roy_kalyan2005@rediffmail.com <p><strong>Objectives:</strong> Sheep butter has been traditionally used in the local villages of&nbsp;upper Himalayan region for its various dermatological benefits.

The goal of the current study is to explore the fiber forming&nbsp;ability of solvent mixture of varying ratios of acetone and acetic acid and&nbsp;to derive the optimized formulation that facilitate the continuous and uniform&nbsp;CA fiber formation.<strong> Methods:</strong> In this study, a new solvent system&nbsp;for electrospinning of cellulose acetate is developed for the preparation of&nbsp;continuous uniform CA fibers. Different concentrations of cellulose acetate&nbsp;are dissolved in solvent system consisting of acetic acid/acetone mixture.&nbsp;The polymer solution prepared was hosted in a mechanical syringe pump,&nbsp;with a stainless-steel blunt end needle fixated to the tip acting as the spraying&nbsp;nozzle. The polymeric cellulose acetate in acetone/acetic acid mixture&nbsp;was examined for its viscosity and electrical conductance. Moreover, the&nbsp;formed cellulose acetate-based fibers were&nbsp; morphologically examined.&nbsp;<strong>Results:</strong> The solvent system composition as well as the cellulose acetate<br>concentration affected the final CA fiber morphology, where the 10%&nbsp;cellulose acetate solution in acetone: acetic acid at 9:1 ratio presented&nbsp;uniform fiber morphology with a diameter of 549±45 nm. The solvent system<br>optimized preserved continuous and uniform, beads-free CA fibers.&nbsp;<strong>Conclusion:</strong> In the current study, the different solvent systems studied&nbsp;presented different fiber morphologies and diameter sizes thus preserving<br>the importance of the solvent system for the cellulose acetate fine fiber&nbsp;production.</p> 2020-03-12T00:00:00+00:00 ##submission.copyrightStatement## http://jpionline.org/index.php/ijpi/article/view/554 Pharmacognostic Evaluation of Fruits and Leaves of Annona muricata L 2020-03-14T06:08:46+00:00 Swapna Birendra rssiddamsetty@rediffmail.com Harisha Ramappa rssiddamsetty@rediffmail.com Satvik Kotha rssiddamsetty@rediffmail.com Raghavendra Rao M rssiddamsetty@rediffmail.com Ramachandra Setty Siddamsetty rssiddamsetty@rediffmail.com <p><strong>Objectives:</strong> Adulteration in marketed samples has been considered as huge draw-back in fortifying quality herbal products.
