Resumo: | The number of cases of animals poisoned by plants is increasing every year and further studies are underway to assess the damage caused by them. Plants containing swainsonine toxic principle cause neurological damage. Damage caused to the reproductive and visual systems has not been described. The objective of this work is to demonstrate by experiment the changes caused by Ipomoea verbascoidea poisoning in the male reproductive system, in the retina and optic nerve in goats. To produce the experimental condition, dried leaves of I. verbascoidea containing 0.02% swainsonine were supplied at a dose of 4g/kg (swainsonine 0.8 mg / kg) in three groups of three animals. The goats in Group I received daily doses of the plant for 45 days and were euthanized on day 46 of the experiment. The goats from Group II received daily doses of the plant for 55 days and were euthanized on day 120 of the experiment. Group III was the control group. The first change, a decrease in semen parameters, was observed on the 14th day of the experiment. On the 20th day, neurological symptoms such as slowness, drowsiness, negative flehmen response and lack of libido were observed in goats 1, 3, 4 and 5. These animals presented decreased scrotal circumference after 35 days from the beginning of the experiment. Between days 35 and 37, all goats showed typical symptoms of LSD, especially motor coordination, ataxia, dysmetria, resulting in impotentia coeundi. In evaluating the serum concentrations of testosterone, there was significant difference between the control group and the groups of poisoned animals. .The main histopathological findings in the reproductive system were observed in the seminiferous epithelium. These were cytoplasmic, vacuolization in Sertoli and germinal cells, a decrease in the Leydig cells, interstitial edema and ogliospermia. There was a reduction of the germinal epithelium, accumulation of proteinacea material in the lumen of the seminiferous tubules and atrophy or absence of stereocilios of the epithelial cells of the epididymis. Alterations of the ocular globe were vacuolization of the retinal ganglion cells, a number of degenerated neurons, and others with intracytoplasmic accumulation of liquid with basophilic characteristics. There was reduced thickness of the optic nerve. The nerve fiber layer close to the optic disc presented an edema and mononuclear inflammatory cell infiltrate. It is concluded that I. verbascoidea poisoning causes testicular degeneration and optic neuritis. |

As plantas que contém o princípio tóxico swainsonina causam danos neurológicos. Os danos causados ao sistema reprodutor e visual não haviam sido descritos. Objetivou-se neste trabalho demonstrar experimentalmente as alterações ocasionadas pela intoxicação por Ipomoea verbascoidea no sistema reprodutor masculino, na retina e nervo óptico em caprinos. Para produzir a doença experimentalmente, as folhas secas de I. verbascoidea contendo 0,02% de swainsonina foram fornecidas em doses de 4g/kg (0,8 mg swainsonina/kg) em três grupos com três animal. Os caprinos do Grupo I, receberam doses diárias da planta durante 45 dias e foram submetidos aos procedimentos de eutanásia no dia 46 do experimento. Os caprinos do Grupo II, receberam doses diárias da planta durante 55 dias e foram submetidos aos procedimentos de eutanásia no dia 120 do experimento e o Grupo III, grupo controle. As primeiras alterações foram observadas no 14o dia de experimento e consistiu na diminuição nos parâmetros seminais. No 20o dia, os sintomas neurológicos foram observados nos caprinos 1, 3, 4 e 5, como lentidão, sonolência, resposta flehmen negativo e ausência de libido. Nestes animais ocorreu a diminuição da circunferência escrotal após 35 dias do início do experimneto. Entre os dias 35 e 37, todos os caprinos apresentam sintomas clássicos de DDL, principalmente incoordenação motora, ataxia, dismetria, resultando em impotentia coeundi. Na avaliação das concentrações séricas de testosterona, observou-se diferença significativa entre o grupo controle e os grupos dos animais intoxicados. Os principais achados histopatológicos no sistema reprodutivo foram observados no epitélio seminífero vacuolização citoplasmática em células de Sertoli e células germinativas, diminuição das células de Leydig, edema intersticial e oligospermia. Houve redução do epitélio germinativo, acúmulo de material proteináceo no lúmen dos túbulos seminíferos e atrofia ou ausência dos estereocílios das células epiteliais do epidídimo. As alterações do bulbo ocular foram vacuolizações nas células ganglionares da retina, nela foram detectados alguns neurônios degenerados e outros com acúmulo intracitoplasmático de líquido com característica basófila. Houve redução da espessura do nervo óptico. Na camada de fibras nervosas próximas ao disco óptico, observa-se um edema acompanhado de infiltrado de células inflamatórias mononucleares. Conclui-se que a intoxicação por I. verbascoidea causa degeneração testicular e neurite óptica.Submitted by Mario BC (mario@bc.ufrpe.br) on 2022-07-19T11:47:15Z No. of bitstreams: 1 Ana Lizia Brito da Cunha Schlobach.pdf: 1067825 bytes, checksum: 143b9420e85061bca9f57456afa49021 (MD5)Made available in DSpace on 2022-07-19T11:47:15Z (GMT).

The number of cases of animals poisoned by plants is increasing every year and further studies are underway to assess the damage caused by them. Plants containing swainsonine toxic principle cause neurological damage. Damage caused to the reproductive and visual systems has not been described. The objective of this work is to demonstrate by experiment the changes caused by Ipomoea verbascoidea poisoning in the male reproductive system, in the retina and optic nerve in goats. To produce the experimental condition, dried leaves of I. verbascoidea containing 0.02% swainsonine were supplied at a dose of 4g/kg (swainsonine 0.8 mg / kg) in three groups of three animals. The goats in Group I received daily doses of the plant for 45 days and were euthanized on day 46 of the experiment. The goats from Group II received daily doses of the plant for 55 days and were euthanized on day 120 of the experiment. Group III was the control group. The first change, a decrease in semen parameters, was observed on the 14th day of the experiment. On the 20th day, neurological symptoms such as slowness, drowsiness, negative flehmen response and lack of libido were observed in goats 1, 3, 4 and 5. These animals presented decreased scrotal circumference after 35 days from the beginning of the experiment. Between days 35 and 37, all goats showed typical symptoms of LSD, especially motor coordination, ataxia, dysmetria, resulting in impotentia coeundi. In evaluating the serum concentrations of testosterone, there was significant difference between the control group and the groups of poisoned animals. .The main histopathological findings in the reproductive system were observed in the seminiferous epithelium. These were cytoplasmic, vacuolization in Sertoli and germinal cells, a decrease in the Leydig cells, interstitial edema and ogliospermia. There was a reduction of the germinal epithelium, accumulation of proteinacea material in the lumen of the seminiferous tubules and atrophy or absence of stereocilios of the epithelial cells of the epididymis. Alterations of the ocular globe were vacuolization of the retinal ganglion cells, a number of degenerated neurons, and others with intracytoplasmic accumulation of liquid with basophilic characteristics. There was reduced thickness of the optic nerve. The nerve fiber layer close to the optic disc presented an edema and mononuclear inflammatory cell infiltrate. It is concluded that I. verbascoidea poisoning causes testicular degeneration and optic neuritis. |
