RESUMO
The pharmacognostic and phytochemical investigations on the leaf, stem bark, and fruit of Zanthoxylum armatum were carried out. Macroscopic study of leaf, stem bark, and fruit of Z. armatum revealed some of the characteristic features like size, shape, color, odor and taste of the crude drug. Distinguishing fragments were identified from the powder drug. Leaf, bark, and fruit powder of this plant have higher values of total, acid insoluble, and water soluble ash as compared to the powder of this plant exhausted with ethanol and n- hexane. Extraction values in methanol were highest for leaves [20.10%] and fruit [11%], while bark showed highest value in chloroform [8.5%]. The extractive values varied among other parts with different solvents. Fluorescence analysis of the Z. Armatum leaf, stem bark, and fruit powder with various reagents showed characteristic coloration at day and under UV light. Quantitative phytochemical screening revealed the presence of many bioactive constituents in leaves, such as alkaloids [15.60+/-0.10 mg/g], sterols [71.60+/-0.10mg/g], saponins [21.57+/-0.12mg/g], tannins [34.43+/-0.21mg/g], phenols [11.66+/-0.33mg/g] and flavonoids [13.68+/-0.66mg/g]. Alkaloids [19.60+/-0.10mg/g], sterols [33.83+/-0.29mg/g], saponins [14.78+/-0.10mg/g], tannins [28.62+/-0.13mg/g], phenols [16.48+/-1.33mg/g] and flavonoids [18.33+/-1.22mg/g] were reported form the bark, while fruits were reported to have alkaloids [25.07+/-0.21mg/g], sterols [164.92+/-0.14mg/g], saponins [28.60+/-0.10mg/g], tannins [35.5+/-0.5mg/g], phenols [21.68+/-0.44mg/g] and flavonoids [22.8+/-1.33mg/g]. Z. armatum is an important medicinal plant, traditionally used for various ailments. This study will be helpful in the future pharmacognostic standardization of this important plant
RESUMO
In spite of the fact that inflammation has been regarded as a localized or generalized defensive component of the body to different types harmful stimuli, there has been becoming confirmation of its strong part in initiation or progression of different ailments particularly related with cancer
Objectives: Aim of this study was to recognize the pattern of expression and level of intensity of COX-2 in different grades of papillary urothelial carcinoma of urinary bladder along with significance of COX 2 in tumerogenesis of urothelial carcinoma of urinary bladder
Period: 1.1.2009 to 31.12.2012
Methods: The marker of COX-2 was investigated by using Immuno- histochemistry
Results: COX 2 was not detected in normal urothelium, but its intensity was expressed as 68% in low grade, 72% in high grade and 80% in invasive urothelial carcinoma
Conclusion: Results of the present study indicate that COX-2 as a component of inflammation play an important role in progression of urinary bladder tumor and encourage use of COX 2 inhibitors as potential antitumor agent
RESUMO
The aim of the study is to record the frequency and pattern of missing maxillary teeth in a sample population of Karchi, Pakistan. A total of 4000 patients were screened at Dr. Ishratul-Ibad Institute of Oral Health Sciences, Karachi. Out of the total, 3621 patients were selected for the study, Student's test was used to analyzed the data using SPSS 10. Total missing maxillary teeth were 2197 [60.6%] out of the total molars were 1119 [30.9%], premolars were 537 [14.8%], canine 156 [4.3%] and incisors 385 [10.6%].No significant difference was seen between male and female. The present cross sectional study formulates a base line data to depict the pattern of tooth loss and its frequency in our Pakistani population
