Purpose: To determine if there is an influence of the Water Drinking Test (WDT) on central corneal thickness (CCT) due to the sudden change of osmolarity since an increase on CCT could lead to a false higher IOP reading on applanation tonometry. Methods: 38 glaucomatous or glaucomatous suspect patients without ocular hypotensive medication were submitted to WDT. CCT was measured by ultrasound pachymetry before and

The present study achieves the biochemistry partial characterization of the chitinolytic extract produced by an endophytic streptomyces sp. strain (A8). This extract was also tested against Anthonomus grandis, the cotton boll weevil aiming its control. The chitinase crude extract from the A8 strain was cultured for five days in a minimum liquid media supplemented with chitin. The extract was partially characterized by standard methods. The chitinolytic extract had an optimum temperature of 66 ℃ and an optimum pH between 4 to 9 (around 80% of relative activity). We also characterized the temperature and pH stability and measured the effects of enzyme inhibitors. The filtered chitinolytic extract was added to an artificial boll weevil diet. Boll weevil development from the egg stage to the adult stage was prolonged, and the percentage of adults that emerged was approximately 66% less than on control diet. This study showed that the larval development of A. grandis was inhibited by the presence of characterized chitinolytic extract in artificial diet. This work provides an experimental basis for using the chitinase from an endophytic bacterium streptomyces sp. as a biocontrol alternative to controlling the plant pest A. grandis.

Porokeratosis is a rare group of keratinizing diseases. It is inherited as an autosomal dominant disease with variable penetrance, although sporadic cases are often reported. Porokeratosis has as its histological hallmark the typical corn oid lamella. Porokeratosis lesions localized on the face can vary from superfici al to destructive in nature. Only 12 cases have been reported in the literature to date. We report one more unusual case of destructive facial porokeratosis.

Background. Cutis laxa is an uncommon entity characterized by laxity of the sk in, which hangs in loose folds, producing the appearance of premature aging. It can be subdivided into congenital and acquired. This latter variant is rare and the skin involvement varies from generalized to localized. We report a case of a localized acquired cutis laxa confined to the face, without preceding inflammat ory lesions or systemic compromise. Four similar cases have been reported to dat e. The etiology remains unknown and there is no definitive treatment. Methods. A 27-year-old White woman came to our hospital with a wrinkled face, pendulous earlobes and drop eyelids. Changes began 5 years prior, and she appeared much ol der than her age. Results. Histological analysis and ultrastructural examination of skin biopsy revealed reduction and fragmentation of elastic fibers, confirmi ng the diagnosis of cutis laxa. No systemic involvement was diagnosed. The patie nt was submitted to plastic surgery for repair, with satisfactory results to dat e. Conclusions. Acquired localized cutis laxa confined to the face without prece ding inflammatory lesions is extremely rare. The etiology remains unknown. Clini cal features and histopathologic findings confirm the diagnosis. surgical repair seems to be the only therapeutic choice, but the results are variable and tempo rary.

＜正＞A data assimilation system （das） was developed for the Chinese Unified Atmospheric Chemistry Environment-Dust （CUACE/Dust） forecast system and applied in the operational forecasts of sand and dust storm （sDs） in spring *** system is based on a three dimensional variational method （3D-Var） and uses extensively the measurements of surface visibility and dust loading retrieval from the Chinese geostationary satellite *** results show that a major improvement to the capability of CUACE/Dust in forecasting the short-term variability in the spatial distribution and intensity of dust concentrations has been achieved,especially in those areas far from the source *** seasonal mean Threat score （Ts） over the East Asia in spring 2006 increased from 0.22 to 0.31 by using the data assimilation system, a 41% *** assimilation results usually agree with the dust loading retrieved from FY-2C and visibility distribution from surface meteorological stations, which indicates that the 3D-Var method is very powerful for the unification of observation and numerical modeling results.
