Me ka hoʻoikaika ʻana e pāpā i nā pōkā i hoʻokumu ʻia ma ke ʻano he olakino olakino a me ka pōʻino o ke kaiapuni, ke hōʻike nei nā ʻepekema i nā hōʻike hou e hiki ʻole i kahi mea ʻē aʻe mua no nā pōkā - tungsten - ʻaʻole ia he pani maikaʻi. ʻo ka ʻōnaehana pale i nā holoholona, ​​ʻike ʻia ma ka puke moʻolelo ACS ' Chemical Research in Toxicology.

Ua wehewehe ʻo Jose Centeno a me nā hoa hana ua hoʻokomo ʻia nā alloy tungsten ma ke ʻano he pani no ke alakaʻi i nā pōkā a me nā mea kaua ʻē aʻe. Ma muli o ka hopohopo e hiki ke hoʻopōʻino ke alakaʻi mai nā pū i hoʻopau ʻia i ka holoholona hihiu ke hoʻoheheʻe ʻia i loko o ka wai i loko o ka lepo, nā kahawai, a me nā loko. Ua manaʻo ka poʻe ʻepekema ʻo ka tungsten he mea ʻawaʻawa ʻole, a he "'ōmaʻomaʻo" pani no ke kēpau. Ua manaʻo ʻia nā haʻawina hou, a me ka liʻiliʻi o ka tungsten i hoʻohana ʻia i kekahi mau pūhaka a me nā kuli, ua hoʻoholo ka hui o Centeno e hōʻiliʻili i nā ʻike hou aʻe e pili ana i ka tungsten.

Ua hoʻohui lākou i nā mea liʻiliʻi o kahi pūhui tungsten i ka wai inu o nā ʻiole keʻena, i hoʻohana ʻia ma ke ʻano he pani no nā poʻe ma ia noiʻi, a nānā i nā ʻōpū a me nā ʻiʻo e ʻike pono i kahi i pau ai ka tungsten. ʻO nā kiʻekiʻe kiʻekiʻe o ka tungsten aia i loko o ka spleen, kekahi o nā mea nui o ka ʻōnaehana immune, a me nā iwi, ʻo ke kikowaena a i ʻole "marrow" ʻo ia ke kumu mua o nā cell āpau o ka ʻōnaehana pale. ʻO ka noiʻi hou aʻe, e ʻōlelo lākou, pono e hoʻoholo i nā hopena, inā loaʻa, hiki i ka tungsten ke hana i ka ʻōnaehana pale.
