A brief historical review of the various mandibular prostheses toghether with a critical analysis of the problem of indications, with special reference to malignant tumors. The reasons for the choosing intert metallic materials are explained and the progressive working out of a new mould of prosthesis is described. The prosthesis implants are in a new metallic alloy, CoTi 68 inox, which is biologically inert and stronger that other material; they are provided with mobile segments and a condyle which may be adjusted during the operation. The prosthesis is inserted into the contralateral normal bone by means of a movable, retating, self-centre ring basket, which can be fixed at the desired point. The flathead screws inserted into the laminae are made of the same material. All the parts are supplied in a sterilizable container, ready for use.

Netra is considered as one of the very important organs in human body. Chakshushya dravyas are the materials which are believed to be beneficial for eyes, henceforth usages of those Dravyas are recommended in various contexts of Sushruta Samhita. In the light of this knowledge and based on Rasadi gunas of Chakshushya dravyas explained in Ayurveda, a critical analysis of those dravyas is done to find out the logic behind the labelling of ‘Chakshushya dravyas’. Triphala, Ksheera, Madhu, Ghrita, Prapaundarika, Saindhava, Yava, Shatavari, Mudga, Jeevanti, Patola are critically analyzed. Even though most of the Chakshushya dravyas are predominantly Madhura rasa dravyas, there are dravyas that are Katu and Kashaya rasa predominant which are seldom told as Chakshushya. Tikta rasa is not considered as Chakshushya but some of the Chakshushya dravyas are Tikta rasa Pradhana. Majority of Chakshushya dravyas possess Rasayana, Brimhana, or Vrishya properties and all of them are not directly contributing to vision. There are ‘Chakshushya Rasayana’ dravyas i.e., dravyas which directly enhances the vision and other dravyas which pacifies the underlying diseases of eye and prevent the secondary manifestations.

Common Action

In all languages where there exists a certain amount of intellectual culture, manifesting itself in the oral or written form of what is called Literature, there must always coexist with it an inferior stratum or platform of speech; the platform of common colloquial intercourse of the mass of the people, and specially of the peasantry and lower classes. The necessity of this bistratification arises from the diverse class of ideas, and the diverse style of intercourse, pervading the two platforms. Language is a growth that flows from the intercommunion of associated persons working out, within a certain bounded circle, the vocal expression which their ideas, their energies, and their circumstances demand for the purpose of common action.

Biting Behaviour

It is felt that the 24-hour catch presents a valuable method of studying the biting-behaviour of mosquitos in the field, and further that conclusions concerning seasonal abundance, vertical distribution and times of biting-activity must be based on catches of this type if serious errors of interpretation are to be avoided.The time-divisions of the catch should not exceed one hour, and even shorter intervals may be desirable. Timing should be related to the actual times of sunrise and sunset. Where possible, a series of consecutive catches should be carried out, and a shift system must be carefully considered in relation to the particular series projected.Usually the results from different levels above ground should be treated separately in working out biting-cycles, and this may also apply to results from different seasons or different localities. Further, while in some instances the summation of long series of catches seems permissible, in others it is not, and in these detailed analysis of the figures may be necessary before consistent behaviour-patterns become apparent.In cases where a measure of the central tendency is to be employed, the geometric mean as modified by C. B. Williams appears to be the most suitable.

Dental Casting Alloys

Castability is, along with biocompatibility, one of the most important characteristics of metallic materials used for dental prosthetic applications. In addition, the characteristics and performance of the employed casting machine are also decisive for the end result of the casting, especially when dealing with titanium or a titanium alloy. Starting from a critical analysis of the existing methods for determining the castability of dental alloys, the current paper presents a new method (and associated pattern) for determining the castability. Also, given the castability’s dependence on the type of casting machine, the paper includes an analysis of suitable casting machines and suggests some possible improvements.

This article deals with the historical review of domestic and foreign medical geography with the use of new facts? Analysis of modern state of investigations and evolution of views on medical geography objects. Directions and tendency of its acceleration development in this country and basis for working out appropriate forecast are being worked out. The article reveals the following problems: elaboration of methods and criteria of medicalgeographical appraisal of natural-territorial and territorial-production complexes, differentiation of geographical environment from the point of view of its influence on the health of population and medical geographical division of territory into districts.
