Midgut juices were prepared from Adoxophyes sp., smaller tea tortrix (STT); Bombyx mori, silkworm (SW); Spodoptera litura, common cutworm (CCW); Plutella xylostella, diamondback moth (DBM); and Musca domestica, housefly (HF) and immobilized onto Sepharose 4B. delta-Endotoxins (ICPs) from Bacillus thuringiensis subsp. kurstaki HD-1 and HD-73 were digested by these immobilized gut juice proteases. All gut juices tested derived relatively proteolytic resistant cores from ICP. The molecular sizes of these cores, about 55 kDa in SDS-PAGE, were resulted. In the case of CCW, however, digestion was very strong and only 1/20 concentration of core protein remained relative to other digests. The N-terminal amino acid sequencing of the core proteins showed that they were truncated at the very end of the N-terminus of protoxin, CryIA, at different sites. Although housefly larvae were completely insensitive to active toxin, the gut juice produced the core, suggesting that the housefly may lack the binding sites for the core-active toxin.

We have previously recovered herpes simplex virus type 1 (HSV) from the corneas of latently infected mice by cultivation in vitro. It could be argued, however, that these data do not definitively distinguish between persistent and latent corneal infection. We have now used RNA hybridization in situ to resolve this question by determining the expression of HSV genes in the corneas of BALB/c mice during latent infection. Two to four months after topical corneal inoculation with HSV, when no active ocular disease or infectious virus was present, corneas were removed and digested with collagenase. Dissociated cells pooled from two corneas were hybridized with 3H- or 35S-labeled 2.6-kb single-stranded RNA probes to detect sense and antisense ICP-0 transcripts. Twenty-five percent of the pools hybridized with the probe for antisense ICP-0 (latency-associated transcript, LAT), while only 3% hybridized with the probe for ICP-0 (p less than 0.03). Of the cells in positive pools, 0.6-7.0% showed a positive hybridization signal for LAT. No infectious virus was found by culture of supernatants from the probed pools or control latently infected corneas. These data provide further evidence that HSV can establish a true latent infection in the mouse cornea.

Contaminated cattle feed was imported into the UK in 1989 and resulted in lead toxicity in some animals. Rapid analyses for lead and several other possible contaminating elements were required for feed and cattle tissues. Microwave dissolution of samples with measurement by ICP-MS was used for multi-element determinations. Lead was found to be the major contaminant. Lead levels in milk samples were measured by several laboratories during the crisis and an analytical quality assurance scheme was devised to monitor the quality of the data. The scheme allowed any poorly performing laboratories to be rapidly identified and excluded from the survey.

The evolution of the actin cytoskeleton after trypsinization and recultivation as well as the effect of the PGE2 modulator and that of the secondary messenger, the cyclic AMP upon the same cytoskeletal proteins in human pulmonary fibroblasts (ICP-23) were studied. The substances were administered simultaneously and after one hour of viral adsorption. Using epifluorescence for pointing out filamentous actin the modifications occurring in this cytoskeletal protein when contacting trypsin and the virus and when PGE2 and cAMP are administered in the experimental variants are observed. Actin arrangement is obviously modified by the viral infection but the restrictive effect of PGE2 and cAMP upon virus replication is correlated with modifications occurring in the actin cytoskeleton.

Two groups of 50 children were included in a study to examine the use of atracurium and vecuronium. In both groups, newborns and infants showed a shorter onset time and a longer clinical duration of the first dose of the neuromuscular blocking drug. The duration of subsequent doses in the various age groups was not significantly different. Atracurium and vecuronium both have a short recovery index, good cardiovascular stability and do not interfere with ICP. The Authors emphasise the importance of monitoring the use of neuromuscular blocking drugs.

The authors examined the records of 30 children with bacterial meningitis to review the role of computed tomography (CT) of the brain in acute management of the disease. CT was normal for 10 patients, six of whom had clinical evidence of raised ICP. CT identified an underlying surgical abnormality in two patients with progressive focal neurological signs. One patient had unsuspected gross hydrocephalus diagnosed by CT, which required neurosurgery. This study shows that the management of bacterial meningitis is influenced by CT in only a minority of cases; for patients with clinical signs of raised ICP, it was found to be insensitive in confirming the clinical diagnosis and establishing an underlying cause. However, CT remains valuable in the management of children with progressive neurological signs for whom neurosurgical intervention may be necessary.

1. The interaction between As and three toxic metals (Cd, Ni and Pb) and Cu (an essential trace metal) in the kidney was investigated in the rat by feeding diets containing various concentrations of As whilst maintaining constant concentrations of the other elements. After 1, 3, 7 and 15 weeks of feeding, metal contents in the renal cortex and medulla, red blood cells and plasma were determined by atomic emission spectrometry (ICP-AES). 2. As accumulated in the whole kidney, whereas Cu accumulated only in the cortex. Accumulation of Cu was found to depend on the feeding period and dietary As concentration. 3. As was also accumulated in red blood cells, where saturation was found at 550 micrograms As g-1 cells. 4. Although Cd was also accumulated in the cortex, its accumulation was independent of the dietary As concentration. Ni and Pb were not detected by ICP-AES. 5. Chromatography of the supernatants from cortical homogenates of control and As-treated rat kidney suggested that Cu accumulated in renal metallothionein (MT). Its accumulation in this fraction was independent of that of Cd, indicating that the As-Cu interaction was not a result of MT induction, but rather that it might result from altered renal handling of Cu with subsequent incorporation into MT.

We have previously developed a reproducible model of transient forebrain ischaemia in rats by bilateral carotid artery occlusion combined with temporary increase of ICP. With this model, reversibility of the energy metabolism and intracellular pH (pHi) was investigated by 31P-MRS during 120 min of recirculation in three groups of, respectively, 30, 60, and 120 min of ischaemia. With the induction of ischaemia, ATP and phosphocreatine (PCr) disappeared, and measurement of pHi showed severe acidosis in all rats. In the 30 min ischaemia group, both energy metabolism and pHi recovered almost completely. In the 60 min ischaemia group, ATP recovered to 74% of control values, but pHi showed full recovery. In the 120 min ischaemia group, ATP recovered to about 50% of control values, and recovery of pHi was variable. Showing logarithmical changes during recirculation in ATP and PCr, the rate of metabolic recovery was fast during 60 min of recirculation, but it decreased and reached plateau thereafter in all groups. Recovery of pHi was affected by ATP levels, and was precipitously accelerated as ATP levels exceeded 50% of pre-ischaemic values. These results suggest that prolongation of the duration of ischaemia limits the restoration of the energy state, and the quality of pHi recovery after cerebral ischaemia is affected by the degree of ATP recovery during 60 min of recirculation.

A sensitive assay using inductively coupled plasma atomic emission spectroscopy (ICP-AES) has been applied to the measurement of trace elements in diaspirin cross-linked hemoglobin (DCLHb) solutions. Calcium, magnesium, zinc and iron were the only elements detected at greater than background levels. Ag, Al, As, B, Ba, Bi, Cd, Co, Cr, Cu, Mn, Mo, Pb, Sb, Se, Si, Sr, Ti, and V were present at concentrations either equal to the acid blanks or were not detected. Detection of non-heme iron (not incorporated into the hemoglobin porphyrin ring) in a 10 g/dL hemoglobin solution required the development of a special protocol. In this protocol a chelator, DTPA, was added to hemoglobin solutions to complex with both free and non-specifically bound non-heme iron. The resulting iron:DTPA complexes were separated from the hemoglobin molecules by ultrafiltration and the ultra-filtrate analyzed by ICP-AES. A modification of this assay in which the DTPA was omitted was used to measure the free non-heme iron in solution. Typical concentrations of chelatable (free and non-specifically bound) and solution (free) non-heme iron in DCLHb production lots at the completion of manufacture were 0.5-1.0 ppm and 0.1-0.3 ppm, respectively.
