1 . HATTERS SHAKE IS ASSOCIATED WITH ( Page 185 ROFM 3rd Edition)

· ARSENIC
· LEAD
· MERCURY
· COPPER

Explanation Notes :

Symptoms: Acid metallic taste, hoarse voice, greyish white coating of tongue, blood-stained stool, circulatory collapse, necrosis of jaw, membranous, colitis, proximal renal tubular necrosis.*
Acrodynia*(Acro-Limbs Odynia-Pain) is seen in mercury poisoning (Pink’s Disease),It is Pain,swelling and parasthesia of Limbs
Mimimata disease—Contamination of fish with mercury, at a place called Minimate Bay in Japan.

Chronic Poisoning: (Hydrar gyrism)

• The symptoms are salivation, sore mouth and throat, fine tremors of the tongue, hands, arms, anemia.

• Shaking palsy is associated with Hg poisoning.

Mercurial tremors are also called hatter’s shakes or glass blower’s shake.(Danbury Tremors)

• Mercurial erethism** is seen in persons working with mercury in mirror manufacturing firms. Erethism is characterized by shyness, timidity, irritability, loss of confidence, mental depression, loss of memory and insomnia. (Psychological symptoms).

• Mercurialentis is a peculiar eye change due to brownish deposit of mercury through the cornea on the anterior lens capsule (Brown-Malt Reflex*). It is bilateral and has no effect on visual acuity

2. DRIED SEMEN ON CLOTHS CAN BE DETECTED BY ( Page 108 )



· INFRA RED
· SPECTROSCOPY
· MAGNIFYING LENS
· ULTRAVIOLET RAY


Explanation Notes:

Seminal Fluid
• Seminal stains have to be detected in cases of rape or attempted rape, sexual murder of the female, sodomy and bestiality.
• Fertility of fluid has to be proved in disputed paternity.
• Seminal fluid choline is originated from Leyding cells.
• Smegma: If the smegma is present around glans of penis, it is suggestive of the fact that an individual did not have sexual intercourse in last 24 hours.
CHEMICAL EXAMINATION
a. Florence test: (Choline Per. Iodide cystols)

• The stain is extracted by 1% hydrochloric acid and a drop is placed on a glass slide.

• A drop of Florence solution (Postassium iodine, iodine and water) is allowed to run under the cover slip.

• If semen is present, dark-brown crystals of choline iodide appear immediately.

• They are rhombic crystals resembling haemin.

• A negative test means the fluid is not semen.

b. Barberio’s test:

• A saturated aqueous or alcoholic solution of picric acid* when added to spermatic fluid, produces yellow needle shaped rhombic crystals of spermine picrate.

• In Barberio’s test, presence of spermine in semen is detected.

• Spermine picrate crystals are seen.

c. The Acid phosphatase test:

• The prostatic secretion element of seminal fluid contains a very much higher percentage of acid phosphatase.

• This test is conclusive in the absence of demonstrable sperms or in aspermia.

d. Creatine phosphokinase: Level of CPK is high in seminol fluids, can be detected in old stains of 6 months.
e. Ammouium molybdate test:

• For semen stains, detect presence of phosphorous.

f. Glycoprotein P₃₀: This test has replaced the quantitative analysis for acid phosphatase.
g. MHS-S1 is also positive and a highly reliable test for semen.
h. Serological typing of the semen is possible by precipitin method.

163. CAUSTIC POISON ERODES MUCOSA BECAUSE



· HYGROSCOPIC IN NATURE
· IT HAS GLUE LIKE ACTION
· IT IS BEING PROGRAMMED TO STICK
· IT HAS AFFINITY FOR MUCOSA


Alkalis include sodium, potassium, and ammonium hydroxide and are bases and hygroscopic in nature thus they dissolve in water. They all contain a positive radical and a hydroxyl group. Alkalis produce a liquefaction necrosis when they come in contact with mucosa and penetrate deeply with full thickness burns common.

Acids cause coagulation necrosis; an eschar forms, limiting further damage. Acids tend to affect the stomach more than the esophagus.

Alkalis ( more damage than acids) cause rapid liquefaction necrosis; no eschar forms, and damage continues until the alkali is neutralized or diluted. Alkalis tend to affect the esophagus more than the stomach, but ingestion of large quantities severely affects both.
