[Effects of treatment with redox agent, blood transfusion and scopolamine on 200 patients with severe chlorphenamidine poisoning].

OBJECTIVE: To verify the effects of treatment with blood transfusion and scopolamine on severe chlorphenamidine poisoning (SCP). METHODS: 400 patients with severe oral chlorphenamidine poisoning were randomly divided into two groups. 200 patients (Group I) were treated with the traditional combined therapy including gastrolavage, purgation and taking redox agent (methylene blue and vitamin C) while the other 200 patients (Group II) in addition to the above mentioned therapy, received blood transfusion and scopolamine injection. RESULTS: The cure rate of Group II was 99.5% and significantly higher than that of Group I (91.0%, P < 0.01). The average time of improving in health in Group II [(8.71 +/- 1.49) h] was obviously shorter than those in Group I [(10.65 +/- 1.72) h, P < 0.01]. Blood methemoglobin concentrations in Group II at 3, 7, 12, 24 h after admission [(43.58 +/- 2.69), (34.21 +/- 2.30), (20.60 +/- 4.03), (13.50 +/- 1.65) g/L respectively] were obviously lower than those in Group I [(54.42 +/- 12.79), (42.17 +/- 22.34), (30.66 +/- 17.67), (19.01 +/- 0.61) g/L respectively, P < 0.01]. CONCLUSION: Blood transfusion and scopolamine had distinctive therapeutic effect on SCP to makeup the deficiency of redox agent. Combination of three therapies may potentiate the detoxication for chlorphenamidine.

Methemoglobinemia induced by chlorphenamidine.

A 76-year old farmer ingested 100 g of chlorphenamidine (Galectron), a plant acaricle, for the purpose of suicide. Gastric lavage was performed and the patient survived. Methemoglobinemia was noted after emergency treatment and was still present at 20 hours after ingestion of the compound. The patient was lethargic for at least 50 hours. Moderate neutrophilic leukocytosis and kidney injury were observed.

[Toxicity of insecticides-acaricides were studied for three phytoghagous mites (Acari: Tetranychidae) using two different laboratory methods (author's transl)].

The aim of this work was to learn the toxicity of acaricides: monocrotophos, chlorobenzilate and chlorphenamidine when used as an immersion and as a spray on the phytophagous mites, Tetranychus (T) urticae, Tetranychus (T) cinnabarinus and Tetranychus (T) ludeni under laboratory conditions. It was concluded that the mite T. urticae was sensitive to chlorphenamidine at least when used as a spray without killing them in a significant level. However the mites T. cinnabarinus and T. ludeni were sensitive to chlorphenamidine when using immersion method. The monocrotophos and the chlorobenzilate were toxic of the three species of mites using though the employed methods.

Acute hemorrhagic cystitis. Industrial exposure to the pesticide chlordimeform.

An outbreak of hematuria occurred from May 20 to May 23, 1975, among employees of a chemical packaging plant. Nine of 22 workers who packaged the insecticide chlordimeform in a separate shed became severely ill with abdominal pain, dysuria, urgency to void, or hematuria. None of 18 persons who worked in other areas of the plant were affected. Four additional workers who had packaged the chemical during the previous year had a history of similar symptoms. Bladder biopsy specimens from three affected persons showed severe hemorrhagic cystitis; chlordimeform and 2-methyl-4-chloroaniline, a metabolite of chlordimeform, were present in urine specimens collected three days after exposure. The illness lasted from one week to two months; the workers recovered completely. Chlordimeform that was injected subcutaneously into three cats produced similar, though less severe, changes in the bladders of two animals.

Content of notification: exposure to the pesticide chlordimeform.

A notification about exposure requires a detailed search of records and interviews with personnel to properly identify potentially exposed groups. Next, these potentially exposed groups must be examined to determine which groups had the potential for highest exposures. The notification should address three key questions: Why am I receiving this notification? What problems are associated with exposure to the chemical? What am I supposed to do? Consideration should be given to notifying lesser-exposed groups, as to why they are not considered to be at increased risk.

Mutagenicity testing of nine herbicides and pesticides currently used in agriculture.

Nine herbicides and pesticides were tested for their mutagenicity using the Drosophila sex-linked recessive lethal mutation assay. These are Ambush, Treflan, Blazer, Roundup, 2,4-D Amine, Crossbow, Galecron, Pramitol, and Pondmaster. All of these are in wide use at present. Unlike adult feeding and injection assays, the larvae were allowed to grow in medium with the test chemical, thereby providing long and chronic exposure to the sensitive and dividing diploid cells, i.e., mitotically active spermatogonia and sensitive spermatocytes. All chemicals induced significant numbers of mutations in at least one of the cell types tested. Some of these compounds were found to be negative in earlier studies. An explanation for the difference in results is provided. It is probable that different germ cell stages and treatment regimens are suitable for different types of chemicals. larval treatment may still be valuable and can complement adult treatment in environmental mutagen testing.

Relaxation of rabbit aorta by chlordimeform.

Chlordimeform N'-(4-choro-O-tolyl)-N,N-dimethyl-formamidine; CDF), an acaracide-insecticide, relaxed helically cut strips of rabbit thoracic aorta and deadventitiated aorta strips. Relaxations by CDF of aorta strips contracted by 5 x 10(-7) M prostaglandin F2 alpha were not altered by the antimuscarinic agent atropine (10(-5) M), the beta-adrenergic antagonist propranolol (10(-5) M), the histamine H2 antagonist cimetidine (2 x 10(-4) M), the dopamine antagonist haloperidol (10(-5) M) or the Na+-K+-ATPase inhibitor ouabain (5 x 10(-6) M). CDF further relaxed deadventitiated strips contracted by 10(-6) M NE or 40 mM potassium and then partially relaxed by 10(-5) M verapamil. CDF (10(-5) M) potentiated contractions caused by the addition of calcium to potassium depolarized strips in zero calcium media, but higher concentrations reduced calcium-induced contractions. The highest CDF concentration (10(-2) M) not only prevented tension increase on calcium addition, but also progressively decreased tension to below baseline levels. The addition of 10(-2) M CDF to aorta strips not contracted by a vasoactive agent decreased resting tension. This relaxation was usually maximal at 10(-3) M and less at 10(-2) M. Thus, CDF relaxes vascular smooth muscle, not by antagonism at the usual vascular relaxant receptors, but by interference with calcium utilization.

Octopamine and chlordimeform enhance sensory responsiveness and production of the flight motor pattern in developing and adult moths.

Octopamine and an agonist, chlordimeform, increase the responsiveness of adult and pharate adult Manduca sexta to gentle mechanical stimulation of the wing. Higher doses of chlordimeform elicit almost continuous production of the flight motor pattern in both adults and pharate adults, and the effect persists for more than 24 h. The dose of chlordimeform necessary for this effect increases with age. Mechanical stimulation of the wing of pharate adults elicits several cycles of flight motor pattern, but with repeated stimulation the animal habituates. Habituation is slower in chlordimeform-treated animals than in controls. Injection of octopamine (1-8 X 10(-8) mol) or chlordimeform (3 X 10(-9) mol) into the mesothoracic ganglion elicits the flight motor pattern. The excitatory actions of both compounds can be blocked by cyproheptidine. Chlordimeform (5 X 10(-8) mol) in acetone applied to the wing does not cause a noticeably greater increase in teh electrical activity of sensory neurons than does acetone applied alone; this result suggests that chlordimeform does not act on these peripheral sites or on axonal membranes in general. We suggest that chlordimeform and octopamine act on the thoracic ganglia to alter the level of excitation or effectiveness of synaptic transmission among central neurons, including those involved in producing the flight motor pattern.
