ABSTRACT
Psoriasis is a chronic, mild and common inflammatory skin condition. Still an ideal treatment for psoriasis, effective, safe, convenient, and economical is not available. In this scenario, the search for suitable alternative treatments with minimal side effects is necessary. Plants can be effective and alternative in this regard. Therefore, this article discusses the leaves of the plants Thespesia populnea (Malvaceae) that are traditionally used in the treatment of psoriasis. The present study aimed to assess anti-psoriatic activity. The dried leaves of the plants were subjected to soxhlation with 95% ethanol and phytochemical studies were performed. The anti-psoriatic activity was evaluated by the Mouse-Tail model. It is a relatively sensitive and reproducible morphometric method that allows quantitative evaluation of the effects of anti-psoriatics through epidermal differentiation. Extracts were applied topically at a dose of 500mg/kg over 14 days and at the end, the animals were sacrificed, longitudinal histological sections were made of the tail skin and the degree of orthokeratosis was determined. It was significantly (P <0.05) increased by the ethanolic extract of Thespesia populnea (52.86±2.86) compared to the control (17.30±4.09). In relative epidermal thickness, the ethanolic extract of Thespesia populnea (92.68±8.8) showed a significant difference (P <0.05) compared to the control (100±10.7). The data obtained suggest that the selected plant has anti-psoriatic activity and confirms its traditional use in the treatment of psoriasis.
ABSTRACT
Wireless network is the fast-growing technology. The world is moving towards the wireless technology and it is used each and everywhere. Wireless network is used in many ways and one of the applications is medical application. In wireless technology, Antennas play an important role in data transmission. Antennas are electronic eyes and ears of humans in the modern world. There are many applications of antenna in medical field. One of the applications is data transmission in wireless capsule endoscopy. Wireless capsule endoscopy is the advancement of wired endoscopy. Wireless capsule endoscopy is used to diagnose the problems in the gastro intestinal tract, stomach and intestines which cannot be identified from outer observation or through x-rays or any other tests. The doctors watch the travel of capsule in the display and diagnose the problems which will be easier for the treatment. The types of antennas in medical field are Ingestible antennas, On body wearable Antennas, Implantable antennas, Antenna for MRI, Microwave Imaging, Thermal Ablation. For wireless data transmission in wireless capsule endoscopy, Microstrip patch (MSP) antenna is designed using Duroid as substrate in the frequency of 2.45 GHz with efficiency of 88% and gain of 4.86 dB. Microstrip patch antenna is selected as it is smaller in size which is most important characteristic of capsule endoscopy. In MSP antenna, copper is used for ground and patch, Duroid is used as the dielectric medium for the substrate as it gives higher efficiency, higher gain and higher directivity.
