Goldschmidt, RB (English spelling) GoldschmidtRB

...Also, when gypsy moths from Japan cross with those from Europe, they produce intersex. RB Goldschmidt hypothesized that the female sex determining factor exists in the cytoplasm of the egg, and the male sex determining factor exists on the Z chromosome (male sex chromosomes are ZZ and females are ZW), and explained that the strength of these factors differs between varieties or with the time of development, and that sex reversal occurs during development, resulting in intersex (quantitative theory). In general, the later an organ develops, the greater the degree of influence of sex reversal, and the longer the developmental period after reversal, the stronger the intersex will be; this is called the law of intersex. ...

From [Parasite Allergy]

...This refers to allergic reactions seen in people infected with parasites, especially helminths, and in researchers who often handle parasites. Richard Benedict Goldschmidt (1910) was the first to recognize allergic symptoms caused by parasites, and described how some zoologists studying roundworms in horses suffered from conjunctivitis, headaches, swelling and pain in the fingers, severe coughing attacks, and asthma symptoms. The reasons why allergic reactions occur due to parasitic infection include the fact that the parasite's body or secretions contain antigenic substances that act as allergens, and that infection easily induces helper T cells that effectively and persistently promote the production of IgE antibodies. ...

…また,マイマイガは日本産のものとヨーロッパ産のものを交配すると間性を生じる。これをゴルトシュミットR.B.Goldschmidtは,雌性決定因子が卵の細胞質中に,雄性決定因子がZ染色体上に(雄の性染色体はZZで雌はZWである)存在すると仮定し,これらの因子の強さが品種間でまたは発生時期で異なり,発生途中で性転換がおこり間性が生ずると説明した(量的学説)。一般に後から発生する器官ほど性転換の影響をうける度合が大きく,転換から後の発生期間の長い個体ほど強い間性になるが,これを間性の時の法則という。…

【寄生虫アレルギー】より

…寄生虫とくに蠕虫(ぜんちゆう)感染者や寄生虫を取り扱う機会の多い研究者などにみられるアレルギー反応をさす。寄生虫によるアレルギー症状をはじめて認めたのはゴルトシュミットRichard Benedict Goldschmidt(1910)で,ウマカイチュウの研究をしている動物学者の中に結膜炎,頭痛,手指の腫張や痛み,激しい咳発作や喘息(ぜんそく)症状を示す者があることを記載している。寄生虫感染によってアレルギー反応が起こる理由としては,寄生虫の虫体あるいは分泌排出物中にアレルゲンとなる抗原物質が含まれていること,感染によってIgE抗体の産生を効果的かつ持続的に促すヘルパーT細胞が容易に誘導されてくることなどが挙げられる。…
