Ntshav siab txo cov nyhuv
Kev tswj ntshav siab yog ua tiav los ntawm kev nce lossis txo qis ntawm catecholamines thiab serotonin hauv nruab nrab thiab lub paj hlwb peripheral. Yokogoshi et al. ua qauv qhia los ntawm kev sim uas muab theanine rau cov nas tuaj yeem txo cov ntsiab lus ntawm serotonin, ua rau txo qis hauv serotonin synthesis hauv lub hlwb thiab nce hauv nws qhov kev puas tsuaj hauv lub hlwb. Thaum cov nas mob ntshav siab (SHR) raug txhaj nrog ntau koob tshuaj ntawm theanine, ntshav siab poob qis, thiab qib qis tau pom tias muaj kev sib raug zoo ntawm koob tshuaj. Ib qho kev txo qis hauv cov ntshav siab tseem ceeb tau pom nyob rau hauv pawg neeg koob tshuaj ntau; Tab sis txawm tias qhov koob tshuaj ntau tshaj ntawm theanine, nws tsis hloov cov ntshav siab ntawm cov nas ib txwm muaj; Txawm li cas los xij, glutamic acid, uas muaj cov qauv zoo sib xws rau theanine, tsis pom tias muaj cov ntshav siab txo qis.
Adjuvant qog suppression nyhuv
Cov kev tshawb fawb tsis ntev los no tau pom tias txawm tias theanine nws tus kheej tsis muaj kev tiv thaiv qog nqaij hlav, nws tuaj yeem txhim kho kev ua tau zoo ntawm ntau yam tshuaj tiv thaiv qog. Adriamycin muaj cov nyhuv inhibitory ntawm qee cov qog, thiab theanine tuaj yeem tiv thaiv qhov concentration ntawm doxorubicin hauv cov qog nqaij hlav, txo cov exudation ntawm doxorubicin los ntawm Ehrlich ascites qog hlwb. Yog li ntawd, thaum theanine siv ua ke nrog doxorubicin, nws tuaj yeem ua rau muaj kev loj hlob inhibition ntawm cov qog nyob hauv 2.1 npaug thiab qhov concentration ntawm doxorubicin hauv cov ntaub so ntswg los ntawm 2.9 npaug. Tsis tas li ntawd, txhaj tshuaj tiv thaiv kab mob qog noj ntshav idarubicin tuaj yeem txo cov qe ntshav dawb thiab cov pob txha pob txha, tab sis thaum siv ua ke nrog theanine, nws tuaj yeem txo cov toxicity ntawm idarubicin thiab txhawb nws cov nyhuv tiv thaiv qog, qhia tias theanine muaj. ib qho kev xaiv tswj cov nyhuv ntawm toxicity tshwm sim los ntawm idarubicin. Thaum cov tshuaj anticancer doxorubicin siv ua ke nrog theanine, nws tuaj yeem cuam tshuam cov metastasis ntawm M5076 zes qe menyuam sarcoma rau lub siab. Tsis ntev los no, Sa dzuka et al. tau kawm ntxiv txog txoj hauv kev uas theanine txhim kho cov tshuaj tiv thaiv kab mob ntawm doxorubicin, thiab taw qhia tias theanine nce qhov concentration ntawm doxorubicin hauv cov qog hlwb los ntawm inhibiting glutamate thauj hauv cov qog hlwb, yog li ua tiav kev txhim kho hauv nws cov tshuaj tiv thaiv kab mob. Theanine muaj txiaj ntsig zoo rau kev kho mob chemotherapy ntawm cov neeg mob qog noj ntshav. Nws tsis tsuas yog txhawb nqa kev ua ntawm qee yam tshuaj tiv thaiv qog, tab sis kuj txhim kho lub neej zoo ntawm cov neeg mob qog noj ntshav.
Relaxing nervous nro, so, thiab lwm yam teebmeem
Terashima et al. pom tias lub ntsiab receptor rau theanine yog lub hlwb. Tom qab dhau los ntawm lub hlwb teeb meem thiab nkag mus rau hauv lub hlwb, theanine ho nce lub intracellular neurotransmitter dopamine hauv hlwb hlwb. Dopamine yog ib qho ua ntej ntawm adrenaline thiab noradrenaline, thiab yog ib qho tseem ceeb rau kev xa cov excitability ntawm lub paj hlwb hlwb. Nws tso tawm tuaj yeem cuam tshuam rau tib neeg txoj kev xav. Tsis tas li ntawd, Yokogoshi et al. pom los ntawm kev siv serotonin (5-hydroxytryptamine) metabolic inhibitors uas theanine tuaj yeem cuam tshuam rau kev sib txuas thiab kev tawg ntawm serotonin hauv lub hlwb. Tom qab noj theanine, cov ntsiab lus ntawm tryptophan hauv lub hlwb nce ntxiv lossis qhia tau tias muaj kev nce ntxiv, tab sis cov ntsiab lus ntawm serotonin txo qis. Theanine tuaj yeem txo qis serotonin synthesis thiab ua rau nws tawg, lossis inhibit serotonin tso tawm.

Tiv thaiv cov nyhuv ntawm lub paj hlwb paj hlwb
Glutamate yog ib qho excitatory neurotransmitter, nrog rau qhov siab ntawm 1mmol-10mmol / L hauv paj hlwb. Thaum cerebral ischemia tshwm sim, cov khoom siv hauv lub cev ntawm O2 cuam tshuam, ua rau txo qis hauv kev tsim cov adenosine triphosphate (ATP), cov khoom siv hluav taws xob hauv lub cell, uas maj mam depletes. Cov cell membrane cais, thiab glutamate raug tso tawm los ntawm qhov chaw extracellular ntau dhau, ua rau cov receptors txuas ntxiv nce cov calcium ions hauv lub cell, ua rau muaj ntau yam enzyme kev ua ub no, thiab thaum kawg ua rau ntawm tes ua rau kev puas tsuaj thiab tuag. Theanine muaj kev sib tw tiv thaiv kev tiv thaiv ntawm glutamate receptors, yog li nws muaj kev tiv thaiv ntawm lub hlwb cov ntaub so ntswg thiab tuaj yeem tiv thaiv lub hlwb paj hlwb tuag los ntawm cerebral ischemia.
Txhim kho kev coj khaub ncaws
Menstrual Syndrome (PMS) yog ib qho kev puas siab puas ntsws thiab lub cev tsis xis nyob uas tshwm sim hauv cov poj niam ntawm 3 thiab 10 hnub ua ntej kev coj khaub ncaws. Juneja et al. tshawb xyuas qhov kev txhim kho ntawm theanine ntawm PMS. 24 tus poj niam tau muab 200mg ntawm theanine txhua hnub, thiab tom qab ob lub hlis, PMS cov tsos mob zoo tuaj, xws li mob taub hau, mob nraub qaum, mob hauv siab, tsis muaj zog, qaug zog, tsis muaj peev xwm mloog, thiab chim siab. Lub tshuab tseem xav tau kev tshawb fawb ntxiv thiab tej zaum yuav cuam tshuam rau cov nyhuv sedative ntawm theanine.
Cov nyhuv poob phaus
Tom qab noj cov nas nrog kev noj zaub mov sib xyaw nrog 0.028% theanine rau 16 lub lis piam, lawv lub cev hnyav poob qis dua piv rau pawg tswj hwm, thiab cov rog hauv plab tau txo qis rau 58% ntawm pawg tswj hwm. Nyob rau tib lub sijhawm, cov qib nruab nrab ntawm cov rog thiab cov roj (cholesterol) hauv cov ntshav txo qis los ntawm 32% thiab 15% raws li, thiab cov roj (cholesterol) hauv daim siab txo qis los ntawm 28%. Yog li ntawd, cov nyhuv poob ntawm cov tshuaj yej yog tshwm sim los ntawm kev sib xyaw ua ke ntawm ntau yam tshuaj yej, nrog rau theanine, uas yog tshwj xeeb tshaj yog zoo hauv kev txo cov roj cholesterol hauv lub cev.

Tshuaj yej haus zoo txhim kho
Khoom noj khoom haus additives
Theanine muaj cov txiaj ntsig ntawm kev txhim kho qhov kev siv ntawm alpha nthwv dej hauv lub hlwb, ua rau tib neeg xav tias so, thiab txhim kho kev nco, uas tau lees paub los ntawm tib neeg kev sim. Yog li ntawd, nws tuaj yeem muab ntxiv ua cov khoom siv rau cov khoom noj, tsim cov khoom noj uas txo cov hlab ntsha thiab txhim kho kev txawj ntse. Piv txwv li, cov tshuaj yej dub yog tsim los ntawm kev ntxiv 5% ntawm cov tshuaj yej dub concentrated extract (Bx=20), 5% ntawm cov suab thaj (Bx=7.5), 15% ntawm granulated qab zib, 1% ntawm gel tus neeg sawv cev, 0.2% ntawm theanine, 0.2% citric acid thiab 0.2% ntawm sodium citrate, thiab ntxiv dej rau 100%. Tom qab 60 feeb ntawm kev noj, lub hlwb tsis tau ntsuas txhua 5 feeb. Cov txiaj ntsig tau pom tias tus nqi ntawm alpha nthwv dej tam sim ntawd nce tom qab noj, thiab tom qab 30 feeb, muaj qhov nce ntxiv, nce mus txog 1.6 npaug. Txoj kev tshawb no kuj tau lees paub tias ntxiv theanine rau cov khoom qab zib, ntau yam dej haus, thiab lwm yam tuaj yeem ua tiav cov txiaj ntsig zoo sedative. Nyiv tab tom ua haujlwm tshawb fawb thiab txhim kho hauv cheeb tsam no.
Txhim kho cov nyhuv ntawm theanine tsw
Theanine tuaj yeem tsis tsuas yog ua cov tshuaj tsw qab ntxiv rau cov tshuaj yej ntsuab, tab sis kuj inhibit iab thiab astringency ntawm lwm cov khoom noj, ua tiav lub hom phiaj ntawm kev txhim kho zaub mov tsw. Cocoa dej haus thiab cov tshuaj yej hom qoob mog muaj qhov txawv txav los yog astringency, thiab ntxiv sweeteners tuaj yeem tsim qhov tsis kaj siab. Yog tias 0.01% theanine siv los hloov cov khoom qab zib, cov txiaj ntsig tau pom tias qhov tsw ntawm cov dej haus tau zoo heev tom qab ntxiv theanine. Txoj kev tshawb no kuj tau lees paub tias nws ntxiv rau lwm yam khoom noj ( kas fes, cocoa, ginseng haus, npias) muaj txiaj ntsig zoo rau kev txhim kho tsw.
