Study of the dynamics of cardiac output in rats with different tolerance to acute massive blood loss showed that the pumping
ability of the heart remains intact during the entire posthemorrhagic period in all high-resistant and in 65% low-resistant
rats. In 35% rats that were low-resistant to blood loss, the cardiac output deficiency syndrome developed after cessation
of bleeding against the background fall in arterial pressure and a decrease in the hepatic blood flow, which are the signs
of rapid variant of the dysfunction produced by acute blood loss.

A forty year old female patient developed paraesthesia of the right side of her lower lip following the placement of an extensive pin-retained amalgam restoration in her lower right second premolar tooth. Radiographs indicated that the mental foramen was close to the apex of this tooth and it was assumed that postoperative pulpitis and periapical inflammation had caused the paraesthesia through the effects of pressure on the mental nerve. The paraesthesia resolved following endodontic treatment of the lower second premolar tooth and the patient has had no further signs or symtoms. 相似文献

The health, growth and development of a cohort of children (n = 59) aged 6
months to 4 years and born after oocyte donation (OD) was compared with
that from a group of children born after in-vitro fertilization (IVF) (n =
126). The study was performed by questionnaire, and the response rate was
100% in the OD group and 95% in the IVF group. All OD children were
healthy. Three IVF children had a neurological disorder. Surgical
intervention had been carried out in 8% of the OD and 13% of the IVF
children. Height and weight development were normal, and eating and
sleeping disorders were uncommon in both groups of children. The IVF
mothers more often expressed concern about the child's behaviour than did
the OD mothers. Thirty-eight percent of the OD parents and 60% of the IVF
parents intended to tell the child about the nature of its conception (P
< 0.01). Although oocyte recipients appear to have more complications
during their pregnancies than conventional IVF patients, the general health
status of OD children aged <5 years is at least as good as that of IVF
children. Growth and development in both groups of children is similar to
that of the general population.

This paper deals with the characterization of a new microparticulate hydrogel obtained by gamma irradiation of α,β-poly[N-(2-hydroxyethyl)-dl -aspartamide] (PHEA). When enzymatic digestion of PHEA hydrogel was evaluated using various concentrations of pepsin and α-chymotrypsin no degradation occurred within 24 h. In-vivo studies showed that this new material is biocompatible after oral administration to rats. PHEA hydrogel was also studied as a system for delivery of diflunisal, an anti-inflammatory drug. In-vitro release studies in simulated gastrointestinal juice (pH 1 or 6.8) showed that most of the drug was released at pH 6.8. In-vivo studies indicated that diflunisal-loaded PHEA microparticles significantly improved the gastric tolerance and oral bioavailability of the drug in comparison with free diflunisal. These results suggest the potential application of PHEA hydrogel as a new delivery system for the oral administration of anti-inflammatory drugs. 相似文献

STUDY OBJECTIVES: To assess the poliomyelitis trend, including study of the epidemiological features, and to correlate this with the immunisation coverage of infants. DESIGN: Three annual lameness surveys in children aged 0-60 months employing cluster sampling methods and a series of five cross sectional surveys of immunisation coverage in children aged 12-23 months of age were undertaken. SETTING: Pondicherry, India, 1988-92. SUBJECTS: More than 10,000 children in the age group of 0-60 months took part in the three annual lameness surveys and samples of 210 children aged 12-23 months were covered each year in immunisation coverage surveys. MEASUREMENTS AND MAIN RESULTS: Altogether 50 of 11,461, 24 of 10,093, and 17 of 11,218 children surveyed during 1989, 1990, and 1991 respectively had become lame as a result of poliomyelitis, giving prevalences of 4.4, 2.4, and 1.5 per 1000 children for the three surveys. The corrected prevalences of poliomyelitis were 5.9, 3.2, and 2.0 per 1000 children during 1989, 1990, and 1991 respectively. The proportion of cases aged up to 36 months fell from 48% in 1989 to 12.5% in 1990 and 6% in 1991. The age at onset was less than 1 year in most. The median age at onset was 10.7 months. About 54% of the affected children had received three doses of oral poliomyelitis vaccine (OPV) before the onset of paralysis. In 1988 immunisation coverage for the third dose of OPV was 91% and in 1992 it was 97.6%. The drop out rate for the first versus the third dose of OPV fell from 6.3 in 1988 to 1.9% in 1992. CONCLUSION: Three successive annual lameness surveys showed that poliomyelitis was declining between 1989 and 1991. Five immunisation coverage surveys conducted from 1988 to 1992 showed high initial coverage followed by an improvement in the form of almost universal coverage for OPV. 相似文献

A comparative study of the parameters of free-radical lipid peroxidation and antioxidant system was performed in children
living in the North for various time periods. Intense lipid peroxidation was shown to be the key factor in the pathogeneses
of several diseases caused by disturbances in the cellular membrane. Decreased resistance of red blood cells to peroxidative
hemolysis is a phenomenon characterizing the adaptation-violating processes.
