Abstract

The main objective of the present study was to induce callus form nodal explants of Phyllanthus niruri and, compared the quantification of Phyllanthin in callus and naturally propagated Phyllanthus niruri. For callus initiation, different sterile plant parts were transferred on MS medium supplemented with auxins either alone like 0.5-2.0 mg/l  2- 4 D or with varied concentration and combinations of cytokinins like 0.5 mg/l BAP and 0.5 mg/l KN. The petroleum ether, chloroform, ethyl acetate, ethanol and aqueous extracts of Phyllanthus niruri plant and callus were prepared and performed its phytochemical analysis. The total flavonoids and polyphenol were investigated to quantify the presence of polyphenol compounds in callus extract and plant extract. The quantification of Phyllanthin in plant extract and callus extract were performed by HPLC. Maximum callus (90.5%) induction from stem/leaf segments on MS medium supplemented with 1.0 mg/l 2,4-D with 0.5 mg/l  BAP (6-benzylaminopurine) within 25 days which was fragile in morphology. Preliminary phytochemical revealed the presence of various secondary metabolites in different extract of plant. The concentrations of flavonoids polyphenol in ethanol extract of callus were higher compared to crude plant extract. Further  Phyllanthin content in callus was found to be significantly increased in response to field grown plants.

Abstract

Heat shock proteins 70 and 90 (HSP-70 and HSP-90) are associated with gastroprotective and ulcer healing potentials. Reports in literatures have shown that age affects gastric ulcer healing, but the role of these heat shock proteins in relation to age has not been fully understood. This study, therefore, investigated changes in the expression of HSP-70 and HSP-90 in the gastric mucosa of 3, 6 and 18-month old rats during healing of Acetic acid-induced gastric ulcers. Male Wister rats (aged 3, 6 and 18 months) were divided into 3 groups according to their ages. Acetic acid ulcer model was used for this study. Ulcer area, oxidative stress, antioxidant markers, HSP-70 and HSP-90 concentration by ELISA and expression by immunohistochemistry was assessed. Results obtained indicate the highest percentage area healed on day 14 in 3 months old rats (100%), while percentage healing for 6 and 18 months old rats was 89.00% and 55.29%, respectively. Malondialdehyde (MDA) concentration was directly proportional to age, while antioxidant enzyme (Superoxide dismutase (SOD) and catalase (CAT)) activities were inversely proportional to age. The concentration and expression of HSP-70 were inversely proportional to age while HSP-90 had directly proportionality to age. The histological architecture also confirmed the faster rate of healing in 3-month old rats recorded in this study.This study indicates that HSP-70 and HSP-90 play different roles in age-related healing of gastric ulcers.

Abstract

An efficient regeneration protocol for Phyllanthus niruriwas developed using nodal explants on MS medium augmented with different concentrations and combinations of plant growth regulators. The highest frequency (85.5%) of bud break and shoot induction was observed on medium supplemented with 1.0 mg/l BAP along with 0.5 mg/l IBA with the formation of 4.2±0.5 number of shoots having length of 3.0±0.1 centimeters within ten days.  MS medium fortified with 1.0 mg/l BAP and 1.0 mg/l Kinetin in combination with NAA (0.5 mg/L) showed the highest percentage (80.0%) shoot multiplicationwith an average of 9.0±0.7 adventitious shoots, directly from the explants, without any callus formation. Shoots formed were remarkable healthy and achieved the length of 10.0±0.5 centimeters in 25 days. Elongated shoots were rooted best on MS medium with 1.0 mg/l IBA producing maximum number of roots with 85% response with average length 8.0±0.3 cm within 15 days. The plantlets were gradually acclimatized and successfully transferred to field condition with 98% survival rate after rooting. The standardized protocol reported in this study may help in large scale propagation of this plant species which is currently exploited from the nature.

Abstract

Effect of occupational exposure to  camphor fumes on the pulmonary function was studied using one hundred (100) selected Igbo women working in camphor industry in Aba,Abia State, Sought East Nigeria, exposed to camphor fumes for over 15years (test subjects). They were compared with age, body weight and height marched control who were mostly house wives and civil servants not exposed to any known fumes or air pollutants and with no history of chest infections or spinal cord injury. Lung function indices investigated to include  Forced Vital Capacity (FVC), Forced Expiratory Volume per second (FEV1),ration of FEV1/FVC expressed as percentage (FEV1%)  and Peak Expiratory Flow Rate (PEFR). The study which lasted for 4 months, was carried out using a Vitalograph Spirometer and Peak  Expiratory Flow Meter. Results obtained  showed  statistically significant reduction in lung function indices (FVC,FEV1 and PEFR)  for workers exposed to camphor  fumes (test)  compared to the  control subjects(P<0.001).  However,FEV1% in the Test group was 89.1% compared with the control (98.0%).Although both groups appeared normal and within normal values with no statistical difference but in some lung diseases like pulmonary fibrosis and other similar lung conditions,FEV1% may  appear normal, yet there is derangement  in pulmonary  functions. This is not the case in this present study which showed restrictive pattern of lung defect as shown by the significant statistical results. The result of mean values of anthropometric parameters which included age, height, body weight and body mass index obtained showed that  the test and control subjects were statistically not significant when compared (P>0.05). It was not possible to determine the effects of environmental factors like carbon dioxide (CO2) carbon monoxide (CO) and other gaseous fumes emitted during the processing period. It is therefore concluded that camphor fumes contributed significantly to the disorder observed in this study.

Abstract

Production of food and its preservation for long time may involve addition of chemicals. Hence, chemical substances can play an important role in food production and preservation. For.e.g. the additives in the food prolong the shelf life of foods; colours, make food more attractive. Flavouring agents like aldehydes make food tastier. Unlike any other industry, agriculture is also a part of industry. The agriculture industry relies heavily on large number of chemicals which may be toxic in nature. Some of these chemicals may get absorbed by our body. Accordingly the use of chemicals involved in production, harvesting (collection), processing, packing, transport, marketing and consumption creates deleterious effect on both human and ecology. Majority of the additives in the food may lead to headache, nausea, weakness and difficulty in breathing. The research on nerve cells has shown these chemicals to cause toxic effect on nerve cells. Although the toxicants cannot be avoided, but the level can be reduced by adopting or making use of organic, sustainable and less toxic options.

Abstract

Lachrymal fluid is isotonic with blood having Associate in nursing isotonicity value like that of a 0.9% NaCl resolution. Ideally, Associate in nursing ophthalmic resolution ought to have this isotonicity value; however the attention will tolerate isotonicity values as low as that of a 0.6% NaCl resolution and as high as that of a two NaCl resolution while not marked discomfort. Some ophthalmic solutions square measure essentially hypertonic so as to reinforce absorption and to supply a level of the active ingredients robust enough to exert a prompt and effective action. The quantity of such resolution used is little as a result of, on administration; the dilution with lachryma fluid takes place apace with stripped discomfort from the hyper tonicity that is merely temporary. However, any adjustment toward isotonicity by dilution with tears is negligible wherever massive volumes of solutions square measure used as colliery to clean the eyes. It is, therefore, vital that solutions used for this purpose be around isotonic.

Abstract

The study aimed to further evaluate the wound healing property of P. nigrum L. using bioassay-guided fractionation method. The ethanolic extract of Piper nigrum L. was fractionated in two stages using column chromatography and preparative reversed phase C18 HPLC, respectively. Significant wound healing properties screened using the scratch wound assay was observed through the cell migration assay in fraction number three (PNE3) out of the 14 fractions, exhibiting 36.7% and 43.8% closure of wound gap within 20 hours at concentration of 0.3 and 1.0 µg/mL, respectively. Sub-fractions which were further fractionated from PNE3 showed comparatively reduced wound healing activity using the same bioassay. The sub-fractions were also compared to Piperine, a major component of P. nigrum L. and the results were comparable. This experimental study revealed that Piperine works together with other compounds in P. nigrum L. to improve wound healing as claimed by those home remedy.

Abstract

Glaucoma is the ultimate commonly acquired optic neuropathy. It signifies a public health challenge since it causes an irreversible blindness. The single known treatment of the disease is decreasing of intraocular pressure (IOP), which has been revealed to lessen glaucoma progress in a diversity of large proportions of clinical trials. Herein in this literature, we briefly define the optical Renin Angiotensin system (RAS) signaling pathway and define the most essential components, physiological actions of major angiotensin peptides, and the Renin Angiotensin system blockers. And discuss the potential implications of their modulators as a new therapeutic target in glaucoma. The literature has shown that the individual RAS modulators including, Angiotensin converting enzymes 1(ACE1) inhibitors, Angiotensin converting enzymes 2 (ACE2) Activators, Angiotensin receptor-1 (AT-1) blocker, and renin inhibitors have a potentials role in modulation of aqueous humour homodynamic, by neuroprotection of the retinal ganglion cells (RGC) and acceleration of the aqueous humour outflow. In conclusion, RAS modulators have an imperious role in lowering IOP, these compounds will pave the approach for prospect innovation, improvement, and publicizing of novel drugs to treat glaucoma and therefore, aid save vision for millions of people suffering with this slow progressive optic neuropathy.

Abstract

The objective of this study is to assess the correlation of body mass index (BMI) with primary dengue viral infection in urban and rural population of district Rawalpindi. Descriptive Cross Sectional Comparative Study. Microbiology Department, Benazir Bhutto Hospital, Affiliated with Rawalpindi Medical College (RMC), Rawalpindi. It was carried out from 1st March 2010 to 30th September 2011. A Stratified random sampling was adopted for 240 (N) subjects residents of urban and rural areas of District Rawalpindi. Urban residents were 144(n) while rural ones were 96(n). The height in meter square and weight in kilogram (kg) were the parameters used to calculate BMI. A 3ml venous blood sample was drawn from each participant for the detection of IgG antibodies against dengue virus by 3rd generation ELISA (Enzyme linked Immunosorbant Assay). The prevalence of primary Dengue viral infection (DVI) for urban residents   according to the current study is 34.7% (n=50 out of the total 144 subjects).  While 19.7% prevalence of primary DVI (n=19 out of the total 96 subjects) was noted for the residents of Rural strata. The correlation of primary DVI with five categories of BMI amongst urban and rural residents is evaluated by applying chi square test. The p-Value was not found to be significant for any of the five categories of BMI either an urban or rural resident. There is no significant association of primary dengue viral infection with BMI of an individual.
