The capability of higher ascomyceteous fungi to cause typical soft-rot decay for wood under laboratory conditions is reviewed and discussed. Fungi tested were extremely active in the decomposition of timbers. Scanning electron micrographs illustrated typical soft-rot decay pattern of higher wood decay ascomycetes, with the exception of H. trugodes that caused white-rot decay. Most of the fungi tested could be grouped as soft-rot fungi that showed typical soft-rot type II. Hypha confined primarily to the resin canals in softwoods or vessel elements in hardwoods and spread tracheid to tracheid via pits of cell wall to cell wall with mechanical force.

BACKGROUND: Sustained-release theophylline, which is generally prescribed as a twice-daily equal-dose regimen, is one of the more common asthma treatments. the development of a sustained-release drug delivery technology that enables improved control of the theophylline blood levels represents a significant advancement in both the efficacy and safety of dosing. METHOD: A crossover study was conducted with 25 adult chronic asthmatic patients requiring daily bronchodilator therapy. The study group included thirteen males and twelve females with ages ranging from 19 to 71 years. The overall approach was to place the patients first on the twice-daily preparation(Etheophyl®) for 28 days at 8 AM and 8 PM, and measure the pulmonary function and theophylline level on the 28th day. the patients were subsequently switched to the once-daily preparation(Uniphyl®) in the same daily dose at 8 PM on the 29th day and the same parameters were measured on the 56th day. RESULTS: the mean serum levels of theophylline were 8.18±1.66µg/ml in the Etheophyl®-treated period and 8.00±1.75µg/ml in the Uniphyl®-treated period. In addition, the FEV1 showed 71.40±7.48 percent in the Etheophyl®-treated and 69.18±9.00 percent in the Uniphyl®-treated period. Thus there were no significant differences between the once-daily and twice-daily preparation. CONCLUSION: The results indicated little clinical differences between the two medication. The two drugs are equally effective in controlling asthma over the four weeks of treatment.

Differences in systolic time intervals(STI's) attributable to the types of mechanocardiographs used for their determinations were studied in a total of 341 healthy adult males. The STI's were measured from mechanocardiograms consisting of simultaneously rocorded electrocardiograms, phonocardiograms and carotid arterial pulse tracings obtained by each of three different types of mechanocardiographs in 125, 56 and 160 subjects, respectively. The study revealed that there were slight to considerabe differences among the three groups in the correlation coefficients between the individual STI's and heart rate. Thus, regression equations using heart rate as variables, for those STI's which were significantly correlated with heart rate, differed slightly to considerably among these groups. In addition, the mean values of those STI's and their derivatives, which showed no significant correlation with heart rate, were also silghtly or significantly different among the three groups. These findings suggest that if STI's obtained from patients are to be adequately evaluated at all, each laboratory must define its own normal standards worked out by using its own methods of recording and analysis of the mechanocardiogram, and cannot rely on those proposed by others.

The surgical reconstruction of complex facial injuries have focused on the following; early one-stage repair, exposure of all fracture fragments, precise anatomic rigid fixation, immediate bone grafting, and definite soft tissue management were the main surgical procedures, as in other facial bone injuries. Complex facial bone fractures involving dentition should be managed by the same principles. However, conventional methods can not achieve accurate preinjury occlusion when there are unstable fracture segments, edentulous state, or complex palatal/maxillary and mandibular fractures. Seventeen patients were surgically reconstructed in conjunction with dental impression, model surgery, and fabrication of dental splints to establish better occlusion. Among the facial fractures that had the occlusal problem, maxillary/palatal fractures and complex mandibular fractures, were the major indications for fabrication of acrylic splints. During operation, fracture segments were reduced and repositioned according to dental wear facets of the prefabricated occlusal splint and then temporary intermaxillary fixations were performed. This allowed us to accomplish precise anatomical reduction and rigid intrenal fixations. The postoperative occlusions were acceptible and no complication occurred as direct effects of dental splint. We suggest that fabrication of an acrylic occlusal splint is necessary for the management of complex facial injuries involving dentition.
