Abstract

The body of knowledgeon delusional parasites is incriminates “delusional patients” as having imaginaryexternal and internal symptoms that feel like parasite movements, dismissesthem as psychiatric cases, and confuses cause with effect. We are critical ofthese arguments and believe that the symptoms of crawling and pin-pricking are genuine;just misinterpreted as parasite movements. Based on our research on over 1000 “delusional”patients since 1996 at our Parasitology Center, Inc. (PCI), we have establishedthat the symptoms of crawling and pin-prickingare caused by toxicity fromexposure to chemicals incompatible with host immune system, e.g., dentalmaterials, that alter the propagation of normal nerve impulses. We have alsoobserved that external parasites/organisms including springtails (Collembola),other arthropods, bacteria, and fungi represent only opportunistic infectionsof skin sites compromised by the toxicity disorder involving the elimination oftoxins through the skin. We have described a new pathological disorder,Neurocutaneous Syndrome (NCS) to which justified “delusional parasitosis” andMorgellons disease cases could be assigned. We have developed a protocol forthe resolution of the symptoms of NCS cases. When followed to the letter, allsymptoms of NCS, conventionally called delusional parasites is, are invariablyand irreversibly resolved.

Abstract

Hydatid disease is acosmopolitan , An incident of case of donkey found after anatomy with pulmonaryhydatid cyst infection which showed after make a pathological sections a manychanges, like thick fibrous capsule, remnant of hydatid cyst with calcificationand fibrosis, other fibrous capsule at the periphery capsule with infiltrationof inflammatory cells . A fibrous capsule associated with inflammatory cells inperi and intra capsule were noticed in, other fibrous capsule with calcificationof degenerate hydatid cyst. A marked fibrous capsule with mineralization ofdegenerate hydatid cyst. The lung with many changes, like, a bronchi withhyperplasia and hypertrophy of bronchial epithelial with dilated alveoli, somewith area of congestion. A minimal bronchiolites with hypertrophy andhyperplasia of bronchiolar epithelium and congestion, other with area of pulmonaryfibrosis with mineralization, a pulmonary fibrosis with few and massive inflammatorycells. In conclusion the hydatid cyst showed in donkey indicating moreresistant response than that by sheep and cattle.

Abstract

Natural products derived from plants as an alternative toconventional insecticides for insect control is now a day very popular amongthe IPM practitioners. Plant-derived pesticides are more readily biodegradable.The surface-film, fumigant toxicities and repellent capacity of castor oil, Ricinus communis was studied againstthe stored product red flour beetle, Triboliumcastaneum. Surface film bioassay technique was employed for contract toxicitystudies, and double glass vial capped with polypropylene stoppers were used forfumigation action. The adults of T.castaneum were susceptible to the contract toxicity of the oil at LD50 levelwith the value of 615.28 μg/cm2. For fumigation toxicity, T. castaneum adults were exhibitedLD50 values of 5.52 and 4.05 mg/cm after 24 and 48 h of treatment,respectively. The oil also showed a strong repellent action against adult T. castaneum. A dose dependant arcsinvalues, 50.66, 58.66, 54.66, 27.99 and 33.33 % were obtained after exposure of12, 10, 8, 6 and 4 mg/ml oil, respectively. Castor oil applied to filter papersin the concentration of 2.04, 1.63, 1.22 and 0.00 mg/cm2 significantly (p<0.05) reduced the hatching of T. castaneumeggs and the subsequent survival rate of the larvae. Adult emergence wasalso drastically reduced by castor oil.
